Yunnan :—Open mountain pasture on mountains of the Chungtien plateau. Alt. 11,000 ft. Lat. 27° 55’ N. Plant of. 24-30 inches. Flowers bright yellow with a satiny sheen on exterior. G. Forrest. No. 10,687. July 1913; No. 11,284. Sept. 1913. In fruit. In Herb. Edin.

A magnificent species. It finds it nearest Chinese allies undoubtedly in P. orbicularis, Hemsley and P. reflexa, Petitm. These agree according to descriptions in having orbicular petals, and by that character should be at once diagnosed from P aemula, Balf. fil. et Forrest. P. orbicularis, Hemsley is also a farinose species, which P. aemula, Balf. fil. et Forrest is not, and P. reflexa, Petitm. has reflexed petals as in P. szechuanica, Pax—a character not found in P. aemula, Balf. fil. et Forrest.

P. orbicularis, Hemsl. was discovered by Wilson in the region about Tatsien-lu, and from seed collected by him it was raised by Veitch & Sonin1g06. The plant was figured in the Botanical Magazine under tab. 8135, and a dried specimen of the cultivated plant So preserved in the Kew Herbarium marked Wilson 3003A I have not seen in any collection a native specimen Sy 3003A, and, as the plant has died out of cultivation, this dried cultivated specimen is probably the only material re- presentation of it. I have compared it with Forrest’s plant here described, and there is no doubt about their distinctness.

P. reflexa, Petitm. is a more difficult subject with which to make comparison, as the species is little known. But Petit- mengin’s description is inapplicable to Forrest’s plant con- spicuously as regards the vegetative apparatus which is alto- gether different from that of P. sikkimensis, Hook.—which P. refiexa, Petitm. is said to resemble,—and then the saccate bracts of P. reflexa, Petitm. ought to separate it readily from P. aemula, Balf. fil. et Forrest.

Another yellow-flowered species, P. tsetzouenensis, Petitm. is described as having leaves cordiform at base and also saccate bracts—characters which do not suit P. aemula, Balf. fil. et

Ovarium pyriforme; stylus brevis tubo calycino vix longior ; stigma magnum discoideum.

Species sectionis Geranioidis habitu repente, foliis, umbella pauciflora satis distinguenda.

Tibet. Farrer and Purdom. No. 178. 1914. Banks of very deep moss and woodland decay, only in the very highest woodland zone of the Thibetan forests round the Bei Ling, at II,000-12,000 ft., among the Pyrolas—uniflora and rotundifolia. A most dainty and charming plant, running freely underground, and forming carpets many yards across. Flowers July 21 (prime a little earlier) ; seed mid-October. In Herb. Edin.

This is a most delightful species, quite different from all others of the section Geranioides. The long creeping stolons with slight rooting system are most striking—suggestive of the growth-form of the plants with which it grows in the moss. Stolons occur in many Primulas, but I know of no other species with the type of stolon shown by this plant. That it is com- mensal might be surmised from its habit, and I find. as is usual in plants of its habitat, that its stolons are traversed by a mycelium. Whether, as is the case in Pyrola, Malaxis, and other like plants, the mycelium extends to the leaves, I have not material to

BALFOUR—NEW SPECIES OF PRIMULA. 5

determine, but one may expect to find it there, and that the plant, like its comrades, has the capacity through its guest fungus of fixing for itself from the atmosphere its nitrogen supply.

6 BALFOUR—NEW SPECIES OF PRIMULA.

This is one of the southern forms of the widespread type of P. denticulata, Sm. and a very distinct one it is. Its small rosette of obovate puberulous leaves, from which a scape of great length for the size of the rosette ascends, gives it a well- marked character. The rhizome forms several rosettes, and there may be several scapes ascending from the same tuft. Its calyx has a curious membranous inflated appearance in dried specimens. It is the Chinese representative of the Himalayan P. erosioides (Watt), Balf. fil. et W. W. Sm.

-W. Yunnan. A-tun-tsu. Ona limestone peak, 14,000 ft. - June 1913. FF. Kingdon Ward. No. 511. In Herb. Edin.

Two or three plants collected by Ward under the number 511 but without further designation are all that we have of this distinct species. The habit of the specimens shows that the plant is one of mossy loose soils such as we associate with P. membranifolia, Franch., P. yunnanensis, Franch., and like forms. The delicate rhizome branches are closely invested with the brown dry leaves of previous years. The small flower with a distinct prominent annulus not barbate is a characteristic feature of the plant.

Quite a distinct gible Sowercd species of the section Malvacea. From P. blattariformis, Franch. its nearest ally,

BALFOUR—NEW SPECIES OF PRIMULA. 9

the long-stalked leaves distinguish it at sight, and there are many other easily recognised distinctions some of which I have noted above.

The Malvacea series of Primula is a compact and definite one. The species are all herbaceous forms with coarse leaves and long racemose inflorescences bearing flowers the calyx of which is diagnostic. It is foliaceous with well-developed reticulate venation more or less elevated, and the obconical tube expands into broad spreading lobes. In fruit the whole enlarges to form a platter-like expansion in the middle of which rests the globose capsule, the wall of which is thickened through- out its whole extent. The species now known—not all with completeness—are :—

. malvacea, Franch., P. blattariformis, Franch., P. Tenana, Bonati, P. celsiaeformis, Balf. fil_—all purple or lilac-flowered forms.

P. bathangensis, Petitm., P. pintchouanensis, Petitm.—yellow- flowered forms.

At the time of the Primula Conference I included P. neuro- calyx, Franch., in this section. I was wrong. It finds its nearest allies in the Mollis section.

f P. racemosa, Bonati, which I had not seen at the time of the Conference, and which I upheld doubtfully as a species, I am now able to say, after an examination of a type specimen, that it is only a poor plant of P. bathangensis, Petitm. To make up for the casting out of his P. racemosa, Bonati, I console M. Bonati by raising his P. blattariformis, Franch., var. Duclouxii, Bonati, to the rank of a species. Unfortunately the name Duclouxii has been already attached by Petit- mengin to a microform of P. malacoides, Franch. and the name P. Tenana now given to Bonati’s plant is in honour of its collector Pére Siméon Ten. M. Bonati sent to me a sheet of this for examination. The following is the diagnosis :—

P. Tenana, Bonati: P. blattariformis, Franch. var. Duclouxit, Bonati in Bull. Soc. Bot. France, sér. 4, ix (1909), 465.

A P. blattariformi, Franch. differt foliis mollibus haud scabridis brevibus (4-5 cm. longis, 3-4 cm. latis) basi cordatis profunde lobatis, lobis rotundis ; scapo scabrido haud lanato; pedicellis longioribus (1-2 cm.) ; bracteis latioribus calyce multo breviori- bus; floribus minoribus; forma calycis post anthesin ultra 2 cm. diametientis.

Perhaps the nearest affinity of P. cephalantha, Balf. fil. is with P. pinnatifida, Franch. Broadly, the form of leaf is the same, but P. cephalantha, Balf. fil. is a much more hairy form and never has the bright green foliage that characterises P. pinnatifida, Franch. The inflorescence and flower of the two plants differ. In P. cephalantha, Balf. fil. the head is more spicate, the outer bracts have a broad sheathing base, the posterior calyx lobe is not denticulate and the others are rarely acute, the corolla lobes are not imbricate and have not the broad rotundate quite entire shape of those of P. pinnatifida, Franch. Lastly, as the fruit is formed the yellow meal that is developed forms a dense coating on the bracts and calyx—a feature not

seen in P. pinnatifida, Franch. To P. Giraldiana, Pax there is a superficial resemblance, but that plant has bright green leaves with few hairs and without the lobation seen in P. cepha- lantha, Balf. fil. and then the corolla lobes are differently shaped. P. cernua, Franch. which is also distinctly recalled has spathulate leaves.

Western Kansu. Lien WhaShan. 12,000 ft. Coll. Purdom. No. 739. In Herb. Kew. ;

This is a bright species which I have described from Purdom’s dried specimens in Kew Herbarium. Messrs. Veitch have been so good as to present to the Royal Botanic Garden a living plant of a Primula raised from Purdom seeds said to be of this plant, but in its growth so far—it is not a plant of easy cultiva- tion—it does not show the characters of Purdom’s dried speci- mens, but rather impresses me as being the plant described by Maximowicz as P. flava, Maxim.* I have seen no example of Maximowicz’s plant, and Purdom’s dried specimens differ conspicuously from the description of P. flava, Maxim. in the petioles, which are long and narrow (not broad) shorter than the foliage (not ‘‘ much longer ’’) puberulous calyx not tubular and mealy, slightly) shorter than the pedicels. It must be remembered however, that P. citrina, Balf. fil. et Purdom is described from

a limited number of specimens from one collecting, and that P. flava, Maxim. also is described from one collecting by Prze- walski on the Upper Hoangho in Kansu. Further knowledge may modify the view I have expressed.

A remarkable feature seen on Purdom’s specimens is a coarse warting over the surface of the lamina. Mr. M. Y. Orr, Assistant in the Laboratory of the Royal Botanic Garden, has been so good as to examine these warts for me, and reports :—

‘‘ (a) The pustules are groups of enlarged and malformed

cells of the upper epidermis of the leaf.

“« (b) Each cell of a group is full of bacteria—a bacillus sp.— the original living contents of these cells having disappeared.

‘These pustules appear to be bacterial galls,’ but the condition of the specimen makes it almost impossible to say whether the bacillus is the cause of the malformation, or whether it is merely following in the wake of some other causative disease.”

A small Chinese species of which we do not know the fruit, and its position is therefore not yet certain. It recalls in many ways P. minor, Balf. fil. et Ward but the absence of the con- spicuous annulus of that species is a strong diagnostic mark. Instead of an annulus the throat has a fairly dense assemblage of minute hairs at the eye which according to Mr. Forrest is greenish yellow. It is altogether a more delicate species than P. minor, Balf. fil. et Ward and has a flower that is large for the size of the plant, the corolla, Mr. Forrest says, being rose- coloured.

In dried specimens like the East Himalayan P. tibetica, Watt especially the form of that species in which the scape is very short and concealed within the leaves. Perhaps one ought to look at P. fasciculata, Balf. fil. et Ward as the West Chinese representative of the Himalayan P. tibetica, Watt. I find no trace of a scape in any specimen, and the flowers are always solitary in the axils of the leaves. The flowers in P. fasciculata, Balf. fil. et Ward do not show the characteristic reflexing of the petals of P. tibetica, Watt. The leaves of P. tibetica, Watt are said to have no meal, but I find it always—especially in young leaves.

Sikkim. Joloong. Alt. 13,000 ft. Very high, near snow. July 1886. Purple. King’s Collector. In Herb. Cal

We know this plant in one set of specimens pa in the Calcutta Herbarium. The collector describes the flowers as ‘“purple,’’ but their aspect in the dried specimens suggests more red than purple and a tint approaching somewhat that of the flowers of its ally P. Kingit, Watt. From P. Kingti, Watt it is readily distinguished by its foliage. The leaves in addition to their oblong obtuse outline never show the pale tint when dry to which Sir Joseph Hooker calls attention in P. Kingiit, Watt, and then the calyx is very different. The ribbing due to the prominent dark veins in the calyx of P. Kingii, Watt is absent, and instead there is a single dark vein running out into each calyx segment. The corolla shows, but in less degree, the velvety puberulousness so characteristic of P. Kingii, Watt but the venation is curiously diverse in the two plants. The veins in the corolla lobes of P. Kingii, Watt

are straight and anastomose in characteristic fashion. Here

n P. Gageana the veins are all undulate and run out through the lobes with hardly an anastomosis. The species is one well worthy of being searched for. It should be a pretty species for cultivation. The roots indicate that the plant grows in a habitat where there is an abundance of soil moisture.

Kumaon. Above Dudhpani. About 13,000 ft. J. E. Reid. 27th July 1886. In Herb. Edin.

This species is known in a few specimens in the Edinburgh Herbarium of a Primula collected, 27th July 1886, by Mr. J. E. Reid, C.1.E., above Dudhpani, at’ an altitude of 13,000 ft., and marked by him as probably a new species. Sir George Watt writes on the sheet bearing Mr. Reid’s specimen: This is the plant collected by Duthie above Napatcha, 13,000 ft., in Kumaon 13.9.84, and named P. near P. elliptica, Royle. It isa perfectly good and new species belonging to the Section Denti- culata, and is near P. Heydei, Watt. Until carefully it might be mistaken for P. Stivtoniana, Watt, and P. tissima, Jacquem. var. spathulata, Hook. f. [P. spathulifolia, Craib]. It is also near P. tenelia, King, a much misunderstood species from the position of the bract being disregarded.”

Duthie’s specimen in Calcutta Herbarium, the only other known, confirms Sir George Watt’s identification, and also both his and Mr. Reid’s comment that the plant is a new species.

BALFOUR—NEW SPECIES OF PRIMULA. 21

The species is very distinct in the series of dwarf tufted Primulas with exannulate corollas. The glandular covering is that of P. Walshii, Craib, but the form of leaf of that species and its involucrally disposed bracts, as well as the flower characters, at once distinguish it. P. spathulifolia, Craib and P. melichlora, Balt. fil. et W. W. Sm. have leaves of form like those of our species, but neither of them is glandular and their inflorescence is not capitular. P. Stirtoniana, Watt is also very different both in form of foliage and in inflorescence. P. minutissima, Jacquem. is altogether a smaller plant with involucral bracts, smaller flowers, and different flower details, and it is not glandular. P. Heydei, Watt is at once diagnosed by its long scape, and there are many other differences.

from P. rosea, Royle and names it P. Harrissii, Watt in his herbarium now at Edinburgh. In his account of Indian Primulas to the Royal Horticultural Society * he refers to it by name as an undescribed species, and nowhere has it been described. I have therefore described it above and add that it is one of the microforms of the aggregate P. rosea, Royle, distinguished from the type plant by its less stature and the smaller mould of allits parts. Also it is apparently not precocious, as P. rosea, Royle is.

P. rosea, Royle exhibits several distinct microforms in its wide distribution over the N.W. Himalaya. It was first de- scribed and figured by Royle + in 1839 in specimens collected at Kedarkante. Five years later Duby f included the species in his monograph and described under the name P. elegans, Duby, a plant—No. 508 of Jacquemont’s in the Paris Herbarium— which he recognised as being near P. rosea, Royle—‘* An revera distincta?”’ Sir Joseph Hooker § cites P. elegans, Duby, as a variety of P. rosea, Royle distinguishing it by its “corolla smaller, tube longer, lobes narrower.’’ Pax || merges P. elegans, Duby in P. rosea, Royle. A curious history attaches to these two forms, P. rosea, Royle and P. elegans, Duby. In 1879 Sir Joseph Hooker figured in the Botanical Magazine (1879), tab. 6437 under the name P. rosea, Royle a plant which had just been introduced to cultivation raised from seeds collected by Dr. Aitchison, ‘‘ which were widely distributed, and from which, I believe, all the plants hitherto cultivated have been grown. We received the first flowering specimen from Mr. Ware of Tottenham ; a few days afterwards it flowered at Kew and in many other collections. It is quite an alpine species. Thomson gathered it at 10,000 ft., and Griffith found it in Afghanistan in snow ravines at II,000 ft. Dr. Aitchison has sent dried speci- mens of what is either a larger form or distinct species from a much lower level, 500 ft. at Gulmarz in Kashmir, and these have much larger obovate oblong and sharply toothed leaves with rounded apices.’”’ In Kew Herbarium is a sheet of Aitchison’s Gulmarz specimens—Aitchison, No. 7. On the sheet is the fol- lowing note by Aitchison: ‘‘See Bot. Mag. tab. 6437. The seeds for raising which were collected from the same locality at Gulmarz.” This tells us that the plant figured in the Botanical Magazine, tab. 6437, is really the larger form which Sir Joseph Hooker suggested might be a distinct species and not the true P. rosea, Royle.

BALFOUR—NEW SPECIES OF PRIMULA. 23

In addition to Aitchison’s specimens from Gulmarz there are in Kew Herbarium specimens from the same locality and from Sumbliali collected on 16th July 1892 by Duthie. An examina- tion of them as well as of Aitchison’s specimens and comparison with a somewhat fragmentary example of Jacquemont’s type in Kew Herbarium received from Paris leads me to the conclusion that the Gulmarz and Sumbliali plants are P. elegans, Duby which is distinct from P. rosea, Royle, and the Botanical Maga- zine figure is therefore a representative of P. elegans, Duby. The plants in cultivation which all came from Aitchison’s seed would therefore be P. elegans, Duby. Seeds under the name P. rosea, Royle have doubtless come to this country frequently since 1879, and the true P. rosea, Royle has been and is probably in cultivation alongside of P. elegans, Duby. It is likely enough that hybrids between them have been raised. This may in part account for the differences that appear in cultivated

’P. rosea, Royle. I have not given special attention to the

cultivated form—and the standpoint is new ; but it is of common observation that some plants are precocious, others coetaneous, some have smaller narrower leaves, others larger broader ones, and then there are the named forms grandiflora, splendens, and probably others. I recollect that the late Mr. Selfe Leonard at one time had several more or less marked forms in his collection at the Guildford Nurseries. All this points to the need for more study of P. rosea, Royle in our gardens.

P. rhodantha, Balf. fil. et W. W. Sm. collected by Aitchison in the Kurrum Valley under No. 462, and by Harsukh under No. 14,931, is another dwarf form of the P. rosea, Royle aggregate with petiolate leaves and a short scape included in the foliage. See p. 39.

P. rosiflora, Balf. fil. et W. W. Sm. found by Harriss (Nos. 16,334, 16,335), and also by Gilg in Chitral, is a more dwarf

microform in which there is almost no scape, the pedicels are

long, and the corolla tube shows a prominently lobed annulus. See p. 41.

P. radicata, Balf. fil. et W. W. Sm.* gathered by Younghus- band in Chitral during 1894, is another dwarf alpine of this series in which the solitary flowers are also embedded in the leaves which are very thick and coriaceous.

26 BALFOUR—NEW SPECIES OF PRIMULA.

This beautiful species belongs to a series of which materials for a complete analysis are still wanting, especially living plants. No one of the series is definitely in cultivation though some may Soon be so. Its immediate Chinese allies are P. argutidens, Franch., P. amethystina, Franch., P. brevifolia, Forrest, and P. silaensis, Franch. P. petrophyes, Balf. fil, may be an alpine microform of it. Then there are the Indian P. Kingiz, Watt and P. Gageana, Balf. fil. All these are purple-blue or claret flowered species. P. Faberi, Oliv. is the only yellow-flowered species of the series as yet known, and it is Chinese.

P. amethystina, Pax * is a chimera and includes P. argutidens, Franch. and P. amethystina, Franch. The two species are distinct as Petitmengin ¢ has shown.

A conspicuous feature in all the forms of the series is the cartilaginous margin of the glabrous somewhat glaucous leaf with sharp recurved teeth in the upper half. The umbel of more or less stalked flowers is secund. The nodding flowers and ampliate corolla limb recall the Soldanelloid Section, but in the foundation form of that section, and in the forms which without. question are co-phyletic, the leaves are pinnatisectly dentate, have no horny margin, and are more or less pubescent.

This seems to be a Northern representative of the Chumbi P. Jaffreyana, King.

The Lhasa plant at first sight seems very different from P. Jaffreyana, King, having longer leaves, much more markedly toothed and less distinctly petioled, stouter and larger scapes, longer bracts and pedicels, and the flower with a larger and tubular calyx with long acuminate segments, the corolla tube is also longer, the annulus less distinctly marked, and the insertion of the stamens not the same. At the same time the Lhasa plant may be only a microform of P. Jaffreyana, King. Both species have a similar leaf construction of a distinct kind. The leaves are somewhat thick, and the upper side has a glistening look in dried specimens, due to the presence of many foveolae of a minute kind at base of each of which is a glandular hair. In dried specimens there are over the surface a number of brown tannin spots.

A series of specimens in the Calcutta Herbarium collected also by Capt. Walton, about Khamba in July 1904, at alt. 16,000 ft., resemble P. /hasaensis, Balf. fil. et W. W. Sm. more closely than P. Jaffreyana, King, yet in some ways seem to be near the latter species. It may be a form connecting the extremes of an aggregate as we know it.

I may note here that Sir George King * refers to P. Jaffrevana, King as apprdching P. tibetica, Watt but differing in its ‘‘ much larger more membranous leaves.” To my eye the plant is really not in the alliance of P. tibetica, Watt which belongs to the series including P. sibirica, Jacq., P. involucrata, Wall., P. Wardii, Balf. fil., while P. Jaffreyana, King has none of the conspicuous bract characters that distinguish them. Its place seems to me to be rather along with such forms as P. florida, Balf. fil., P. hazarica, Duthie, P. Legendrei, Bonati, P. Soultet, Franch. and other forms which constitute a characteristic enough section more or less farinose with leaves more or less stalked without cartilaginous margins, bracts linear subulate pulvinately thickened below at the base, ribbed calyces with parchment intervals, long corolla tubes, and delicate annulus. But at the moment I am not able to fix the limits of sections including such forms.

It is in the way of P. spathulifolia, Craib but has characters which point to its distinctness as a species, and its description as such may lead to special search for more specimens of it through which a clearer ;dea of it will be obtainable than the material now available affords. Mr. Smith’s plants collected late in the year show but a few passed flowers and some bruised capsules.

The plant differs from P. spathulifolia, Craib in the following points :—longer narrowly elliptic not spathulate leaves which are more definitely and acutely cut, the longer farinose flower- pedicel, single bract longer than the pedicel, larger calyx, smaller corolla limb.

This is a dwarf ally of P. pulchella, Franch. There are abundant specific distinctions. Apart from the smallness of stature the shorter leaves are farinose above, pedicels are short and erect, lengthening in fruit as do those of P. pulchella, Franch. The calyx gives a diagnostic mark in the much longer segments. Then the corolla lobes are entire. F inally,

ot far removed, I think, from P. stnuata, Franch.* The leaf outline in the two plants is not quite the same, as I judge from Franchet’s very short description and from a_ photo- graph of a Paris sheet of Franchet’s type. The inflorescence has more flowers, and the scape is stouter and pedicels longer in Maire’s plant. The bracts too are much larger and more - involucrate in P. nemoralis, Balf. fil. Franchet’s plant is so little known that I cannot write about its affinities with the confidence I would like. But I have ample grounds for saying that P. sinwata, Franch., has no place in the Soldanelloid Section of Primula alongside of P. Wattit, King where Pax places it. Pax had not seen the plant and gives it its position on the strength of Franchet’s comment that its leaves are like those of P. Waitii, King; but then Franchet adds the form of corolla and that of the calyx are very different in the two plants.

Hunan. Summit of Yo-Chow. Alt. 10,300 ft. E. E. Maire. In Herb. Edin.

I have not seen enough of P. incisa, Franch., to enable me to obtain a clear picture of its features, and the descriptions are not satisfactory. Franchet’s type came from Muping, collected by David, and all Muping plants are very distinct. This I have not seen. With it Pax associates a plant from Mt. Omei collected by Faber and two plants collected by Pratt at Tatsienlu under the Nos. 31 and 161. In order to do this Pax has to modify Franchet’s description in im- portant particulars.

Franchet regarded his P. incisa, Franch., as near to P. involucrata, Wall., but very distinct by the scabrid leaves with incised lobes. I cannot subscribe to the affinity, but Franchet’s

$ BALFOUR—NEW SPECIES OF PRIMULA. 33

reference to scabrid leaves as diagnostic seems to indicate a prominent mark. Pax, however, describes P. imcisa, Franch. as having also glabrous leaves, and certainly Pratt’s plants have leaves with this character. But Pratt’s plants have not the glabrous scape which both Franchet and Pax describe for P.incisa, Franch. Then Pax introduces the character of golden meal on the pedicels—that is apparent in Pratt’s plant No. 31, and I have seen it on two other specimens—Henry’s No. 134 and Wilson’s No. 4046A in Kew Herbarium. It is surely one that Franchet would not have overlooked in the Muping plant to which he ascribed golden meal sparingly on the calyx. Pax says of the calyx, ‘“ glaber vel intus farinosus.”’

Without doubt P. incisa, Franch. is a type around which are to be grouped microforms which further investigation must sift out.

The species I describe here under the name P. oresbia, Balf. fil., belongs to the aggregate but is certainly different from Franchet’s P. incisa, Franch. and does not belong to Pax’s chimaera. The intensely white farina on the under side of the leaves and all over the inflorescence, and particularly the calyx, is a mark of separation, and I have seen no form amongst those which I have examined with which our plant conforms exactly. Specimens of this imcisa aggregate which I have seen in the Kew Herbarium are Henry, Nos. 134, 8869; Pratt, Nos. 31, 161, 258; Soulié, No. 383; Wilson, Nos. 4046, 40464, 4046B. The form most like P. oresbia, Balf. fil. is Henry’s No. 8869, but it has golden meal. There are also some good specimens in the Herbarium of the British Museum, but I have not yet been able to undertake the task of critical examination and comparison of them and the Kew specimens.

The examination of P. oresbia, Balf. fil. confirms me in the opinion I expressed at the Primula Conference that P. incisa, Franch. does not find its natural place in the Section Soldan- elloides. These two species seem to occupy a position linking Soldanelloides with Bella and Yunnanensis.

unan. Rocky plateaux of Yo-Chow. Alt. 10,200 ft. Flowers blue. Maire. In Herb. Edin.

A small species like a miniature P. leimonophila, Balf. fil. but it has many points of difference, of which I may note specially that of the flower. The corolla tube has a moderate- sized annulus which lies quite at the mouth of the corolla tube, whilst in P. leimonophila, Balf. fil. there is a very large inflated annulus lying a little below the mouth of the tube. The corolla lobes are small and rounded and hardly divergently emarginate. Then the short stamens—I have only seen the long-styled flower—have no interstaminal lobes forming an androecial annulus as in P. leimonophila, Balf. fil. Of other diagnostic characters note the long bracts, short stout pedicels campanulate calyx with the intercostal areas not broad and pergamentaceous, and then the small linear foliage.

It may be this is an alpine microform of P. leimonophila, Balf. fil. but by the features to which I have drawn attention it may be readily recognised.

It belongs to the Amethystina Section.

A charming dwarf species which is so like P. dryadtfolia, Franch. in form of foliage that one might at first regard it as a small form of that species. The leaves are however different apart from size in this, that their upper surface is covered with very short hairs which are absent in P. dryadifolia, Franch. The whole flower structure is different. The scape bears but one flower and is enclosed in the foliage; in P. dryadifolia, Franch. it is pushed out well beyond the leaves. The flower is erect, not slightly nodding. The calyx much shorter than the corolla suffices to tell this species at once from P. dryadifolia, Franch. where the corolla is shorter than the calyx.

Sir George Watt recognised the distinctness of this plant as a species and named it on the Calcutta sheets P. serrata, sp. nov., but he did not publish a description. Unfortunately the name he suggested has been absorbed by Gusmus for a hybrid P. minima x P. Wulfeniana, which is not uncommon in gardens. The plant is the first Indian species as yet known of the Sikkimensis Section which has purple flowers, and its occurrence is of interest because we have already from China both a purple and yellow series of this Section. The only specimens known of P. prionotes, Balf. fil. et Watt are those collected by Capt. Walton during the Tibet Frontier Expedition in 1904.

Microforma P. malacoidis, Franch. foliis minoribus haud late cordatis, scapis tenuioribus decumbentibus diversa.

Yunnan. G. Forrest.

P. malacoides, Franch. is a species with a wide distribution from the Shan States of Burma through Yunnan, both North and South. Over its wide distribution it presents a considerable range of variation, and several of its forms have already been described as distinct species. A supply of material sufficient to justify the mapping out of the microform variations of the aggregate is not yet available, but what we have seems to show that the type may be monocarpic or pluricarpic, and some of the monocarpic forms are annual. The forms range themselves in two series: one in which with generally larger leaves are associated tall scapes with many whorls of flowers—of this P. malacoides, Franch. is the centre; the other with smaller leaves and shorter scapes with one umbel or one or two whorls of flowers—the type of this is P. Forbesii, Franch.

Under the name P. Forbesii, Franch. a plant was introduced to cultivation in 1891 by Vilmorin. It was monocarpic annual. The P. Forbesii, Franch. of cultivation at the present day is pluricarpic perennial forming stout rhizomes. It may be that two different microforms have been cultivated under the name.

Plants of the larger-leaved tall-scaped type we owe in cultivation to Bees, Ltd., raised from seed collected by George Forrest. The first plants raised and flowered —see figure in Gardeners’ Chronicle, Ser. 3, 44 (1908), 396, figs. 164, 165— belonged to the microform here described, not to the true P. malacoides, Franch. as that is shown in the Paris Herbarium and as it appeared later in plants raised also from Forrest’s seed. A distinction between the microforms was not made by Mr. Forrest in the field—and small wonder. Their difference was first noticed in cultivation by Mr. Laurence B. Stewart, who gave the name P. pseudomala- coides to the microform. It is a slenderer plant than true P. malacoides, Franch. with leaves which remain more prostrate and have the oblong rather than the ovate form ; the flowers are

smaller. As yet the thrum-eyed plant only of P. pseudomalacoides, L. B. Stewart has been seen, and no seed has been obtained from it except by crossing with true P. malacoides, Franch. It is readily propagated by division. The fact that it crosses easily with P. malacoides, Franch. means that already in cultivation numerous progeny exist which must be the result of such crossing, and the distinction between the forms easily made when the true forms are seen side by side may not be generally recognised. |

P. neurocalyx, Franch. the flower at the anthopode is densely bearded. The question arises—Is P. riparia, Balf. fil. et Farrer to be considered as a microform of P. neurocalyx, Franch.? In the Obconico-Listeri series we know of such microforms, and it may be we have a like condition here. The plants are cer- tainly much alike.

W. Himalaya, Kumaon. Ralam Valley. Inayat. No. 24,647/b. 18th August 1900. In Herb. Kew.

A single specimen in Mr. Duthie’s herbarium now at Kew is so different from all other Indian Primulas that it is described here as a new species. At first sight it looks some- thing like P. involucrata, Wall. but its leaves are farinose and are distinctly cut on the edge. The aspect of the flower is quite that of P. involucrata, Wall. but there is no annulus in the corolla tube. It resembles P. sibirica, Jacq. in the shortness of the basal sac to the bracts, which is quite unlike that of P. involucrata, Wall. From both of these species it is separated by the long flower pedicels arising from a .Scape so short as to be included in the leaf sheaths. By this it recalls P. tibetica, Watt and like that species it is farinose (the books erroneously refer to P. tibetica, Watt, as “‘ not

mealy’’). Its larger size, want of an annulus, petals not re- flexing readily, distinguish it however from P. tibetica, Watt. It might be regarded as a North-West Himalayan representa- tive of P. tibetica, Watt. On the single specimen available for examination the long pedicels of one of the flowers bears at a short distance below the flower a pair of bracts. This suggested that the specimen might be throughout abnormal and only a short-scaped variation of P. involucrata, Wall. or a long-pedicelled and. large-flowered P. tibetica, Watt or even a P. sibirica, Jacq. modified. The chain of characters in the plant is such however that one cannot regard the suggestion as valid. One must hope for more specimens.

This species, named by Sir George Watt in honour of the Rev. J. Traill of Jaipur, is briefly diagnosed by him in the Journal of the Royal Horticultural Society, xxix (1904). A figure and description of P. tnvolucrata, Wall. are given under the name P. Trai//i.: in the Gardeners’ Chronicle, xxii (1897), 263, from plants grown by Mr. George Wilson. The origin of the confusion Sir George Watt thus explains :—‘‘ The seed I collected of it [P. Tvaillii] was mixed with the only other Primula found in Kulu during that expedition, namely, P. involucrata, Wall. on account of the necessity that existed to economise my collecting materials. On the mixed seed reaching Europe it was found that only P. imvolucrata, Wall. germinated, and thus got talked of as P. Traillit, Watt.”’ P. Trailliai, Watt has not yet come into cultivation.

mensis, Hook, in the group of forms within his Section Pur- purea, which have petals entire or partly emarginate and the throat of the corolla exannulate. In ascribing to P. Traiilii, Watt an exannulate corolla Sir George Watt’s recollection of the plant as he found it ten years previously has not served him well or perhaps he was misled by a somewhat faulty draw- ing by a native artist of dissected flowers attached to his her- barium sheets. No annulus is shown in these. But I find a conspicuous ten-lobed annulus in the flowers of the dried specimens. It may be that the affinity suggested is correct, but I am not satisfied about it. The form of calyx and corolla seems different—there is the annulus—and then the placental column tends to the globular. Unfortunately the critical seeds are wanting in all the specimens.

A species which appears to be a near neighbour of P. kialensis, Franch. P. Umbrella, Forrest differs from P. kialensis, Franch. as described in the much longer scape, obtuse bracts sheathing the pedicels, densely farinose bracts, pedicels, and calyx, costate calyx tube. This dainty species is in cultiva- tion, but is not a rapid grower. The abundance of golden meal all over the plant is characteristic, but the most differentiating mark is found in the inflorescence. The bracts radiate from the top of the scape, each one forming a channel in which a pedicel, twice the length of the bract, lies. The calyx too is

The following is Mr. Reginald Farrer’s description of the plant as he found it in Kansu :—

“Primula No. 6 P. Viola-grandis: Sect. Omphalogramma). ‘Whole plant clothed in whitish glandular hairs. Leaves appearing with the flowers, and developing further afterwards,

springing in a tuft, about 2}-5 cm. in length, ovate-cordate, dark green, thick and flannelly, borne on stout petioles as long as the blade, and often twice as long ; the lowest diminish- ing till they are but small oval-rounded pale tabs. Scape 34-5 inches, greatly exceeding the leaves, each carrying one very large flower. Calyx a cup, cloven to the base in ovate-lanceo- late lobes. Flower rich light violet-blue, of luminous effect, the straight tube more than 34 cm. in length, glandular, pale- purple, slightly and gradually swelling at base and throat. Lobes of the corolla and calyx usually 6, sometimes 5 or 7: those of the corolla open at first in a small regular star of deep violet, but soon lighten, the three upper lobes now lying stiffly back along the tube, and the three lower standing as stiffly outward, so as to make a strangely Gesneraceous effect. Corolla lobes obovate, usually emarginate. Stamens all gathered at the roof of the tube, over the pistil. Capsule globular (?). ©

The capsule is apparently round, the calyx fringed with many teeth; the sp. with its absurd throat, is not at all a free seeder.

he plant is an interesting addition to the Omphalogramma series. Its nearest ally is P. Englert, Knuth a species collected by Soulié at Tatsienlu. I have not seen specimens of P._ Engleri, Knuth, and rely entirely upon the technical description | as a basis for the differentiation from it of P. Viola-grandis, Farrer et Purdom. For purposes of comparison a trans scription of Knuth’s description of P. Englert, Knuth is given

below.* The diagnostic characters are these :—P. Engleri, Knuth has thin papyraceous leaves which are rarely petiolate. Farrer and Purdom say of P. Viola-grandis, Farrer et Purdom that the leaves are very thick and flannelly and have fleshy stalwart stalks. The interpretation of Knuth’s statement that in his plant the scape is destitute of basal scales is not quite clear. No Omphalogramma has scales on the scape, and I must assume that Knuth refers to the bud scales around the foliage leaf tuft. Such scales are distinctly present in P. Viola-grandis, Farrer

et Purdom. en Knuth says nothing about any capitate ae interspersed amongst the long white hairs on the leaves his plant. In P. Viola-grandis Farrer et Purdom these

are abundant and so evident that no careful describer could miss seeing them. In the dried specimens they are bright red ; whether that is the colour in the living leaf I do not know. The scape of P. Viola-grandis, Farrer et Purdom is much longer than the leaves. In Knuth’s plant the scape is described as se slightly longer than the leaves. Knuth says of P. , Knuth that the calyx is widely campanulate. That panded fits P. Viola-grandis, Farrer et Purdom where the calyx tube is a shallow cup. Lastly, in the corolla—the throat in P. Englert, Knuth is said to be densely puberulous with short hairs—its colour is not mentioned; in P. Viola-grandis, Farrer et Purdom the throat is hairless and is whitish. The corolla lobes of P. Englert, Knuth are broadly obovate and retuse slightly incised. In P. Viola-grandis, Farrer et Purdom they are narrowly obovate or spathulate and are emarginate with entire segments. The sum of characters suffices to justify the naming of Mr. Farrer’s plant as a new species, and its area, it will be noted, is some distance from that of P. Engleri, Knuth. Mr. W. W.

Omphalogrammas in P. Elwesiana, King, in Sikkim, to whom I have shown the specimens, concurs in the view expressed of the relationship of P. Viola-grandis, Farrer et Purdom and P. Englert, Knuth.

Farrer and Purdom’s plant has some resemblance to P. vincaeflora, Franch. but is altogether less robust, and the long petioled leaves separate them at sight.

Franchet first pointed out the distinctness of these forms from Primula, and definitely in 1898 * he constituted the genus Omphalogramma for them, having previously in 1885 + been content to place them as a section under Primula. Pax in 1889 { kept up Franchet’s group as a section of Primula, re- naming it Barbatae on the trivial ground that, as seed was known in only one of the three species recognised at the time, the name might not be descriptively accurate of the others. In his monograph of 1905 § Pax reverts to Franchet’s name Omphalo- gramma, but keeps the group as a section of Primula notwith- standing Franchet’s advocacy in his paper of 1898 of its claim to generic rank.

I have had opportunity to examine specimens of all of the known species excepting P. Englert, Knuth. The labours of Forrest and Ward in China and of Cave and Cooper in Sikkim have furnished an ample supply of dried specimens, and through Forrest and Cave we have now living plants in the Royal Botanic Garden, Edinburgh, of P. Delavayi, Franch., P. Elwesiana, King, P. Franchetii, Pax, and P. vincaeflora, Franch. P. Francheti, Pax in fruit is still unknown in Europe. The more I examine the plants, the more convinced I am that Franchet is right in treating Omphalogramma as a genus separate from Primula. I do not lay stress upon vegetative features—their general characters occur in true Primulas, for instance, in P. Gammieana, King, in P. Gambeliana, Watt and others of the so-called Cordi- folia section. The flower and seed characters give quite definite diagnostic marks of generic value, and these are :—

(a) The flower is zygomorphous.

(b) The numerical symmetry of perianth and androecium—

the whorls have commonly six parts, but may be up to eight, and occasionally five.

(c):The stamens have long stout filaments with the anterior ones bending across the corolla tube to complete the cone of anthers at the corolla mouth.

(d) Seeds flat with a broad wing-aril.

56 BALFOoUR—NEw SPECIES OF PRIMULA.

The differences from Primula are much greater than some of those which separate other genera from it—take, for instance, Androsace or Cortusa. The genus of Primulaceae to which Omphalogramma shows most resemblance is the monotypic Bryocarpum which in its species, the yellow-flowered B. himalaicum, Hook. f. et Thoms. is a well known Sikkim plant and is now in cultivation. The whole facies of Bryocarpum is that of Omphalogramma—the petiolate ovate leaves arising within a sheath of scales, the long ebracteate scape with one large terminal oblique flower, the numerical symmetry of the flower, 5-8 parts in the whorls, the calyx cut into narrow segments to the base, the long corolla tube and lobes. Its differences are the less hirsute covering, the stamens with short filaments and longer acuminate anthers, the long cylindric capsule many times the length of the calyx and opening by a stylopodial lid beneath which are found some short valves—in Omphalogramma it is always short ovoid with the upper quarter extruding from the calyx and dehiscing from the style base right down often to the base,—lastly, the oblong ellipsoid seeds with areolate surface. A subordinate character : the ovary of Bryocarpum himalaicum, Hook. f. et Thoms. has a sparse coating of red capitate glands. I have seen nothing of this in Omphalogramma. Those who wish to sink Omphalo- gramma would place it more conveniently in Bryocarpum than in Primula. Were I to write a monograph of Primula I should exclude Omphalogramma. As I am not doing so, I add here the names of the plants that are involved in this Primula~-Omphalogramma discussion, giving them their specific designation under both genera :— Primula Elwesiana, King (1882) =Omphalogramma Elwesiana (King), Franch.

The material of this plant in the Calcutta Herbarium is scanty, but suffices to indicate that the plant has not yet been described.

The plant has in some ways a resemblance with P. Stir- toniana, Watt but its foliage is not the same. The leaves are truly spathulate, and have a crenulate margin which is, however, sometimes dentate, but the leaf has never the obcuneate form and somewhat truncate apex of that of P. Stivtoniana, Watt. The nearly sessile flower and small subulate bract just below the calyx are also different from what is found in P. Stirtoniana, Watt and the calyx is much smaller, as is the whole flower. It may be, however, that this is a microform of P. Stirtoniana, Watt.

Pratt appears to have been the first collector to send home specimens of this plant. It was found later by Wilson and raised from the seed he collected by Veitch, who introduced it to horticulture under the name P. sibivica, Jacq. var. chinensis. It is a great acquisition, one of the freest of growers and seeders, and it is most floriferous.

Its nearest ally is the widespread Himalayan P. involucrata, Wall. which has, however, white flowers, and is thus easily diagnosed. From true P. sibirica, Jacq. both P. Wardii, Balf. fil. and P. involucrata, Wall. are readily distinguished by the long appendages to the bracts—these may be almost as long as the bracts. Were we to accept the most recent technical description of P. sibirica, Jacq. as given by Pax, we should find a diagnostic character from P. sibirica, Jacq. in the large ro-lobed

60 BALFOUR—NEW SPECIES OF PRIMULA.

annulus of P. Wardii, Balf. fil. P. sibirica, Jacq. is said to be exannulate. But I do not assent to this statement. I am not yet prepared to deal with P. sibirica, Jacq. as an aggregate type, because I have not yet had opportunity of seeing the Petrograd collection in which it must be particularly well represented. But I have dissected the flower of the true P. sibivica, Jacq. in such representative specimens as a Dahurian specimen collected by Losnin and in No. 883 of Roskevitz presented to Edinburgh by the Petrograd Herbarium, as well as in Karo’s No. 54 from Dahuria (one of the types of P. szbirica, Jacq. var. brevicalyx, Trautv. cited by Pax). In allofthem I find an excellent annulus. I also find the annulus in European specimens—in that, for instance, collected by Hojman and included in Baenitz Herb. Europ., and also in Magnier’s No. 2558 from Uleaborg, which Pax cites as his var. integrifolia, Pax of P. sibirica, Jacq. In Sir Joseph Hooker’s plant from West Tibet, now in Kew Herbarium, the annulus is beautifully developed, although the Flora of Brit. India, iii (1882), 487, says the corolla is not annulate.’’ All this shows that a critical study of the micro- forms of the aggregate P. sibirica, Jacq. has yet to be undertaken.

P. Wardit, Balf. fil. is the West Chinese form of the siaohetievs’ and is altogether a different plant from the Himalayan P. involu- crata, Wall. These two in turn are not the same as the P. sibirica, Jacq., of the Flora of Brit. Ind., whatever that may be—it is not the North Siberian form of the species. True P. stbirica, Jacq. does not occur in the Himalayas, and the Himalayan plants so named will have to be described under a definite name.

I may add also that a number of Tibetan plants have been wrongly assigned to P. sibirica, Jacq. and another series of Tibetan forms has been named in herbaria P. tibetica, Watt, var. intermedia—being regarded as a passage between P. tibetica, Watt and P. sibirica, Jacq. But P. tibetica, Watt does not run into P. sibirica, Jacq. The former is not a dwarf state of the latter. P. tibetica, Watt is apparently a widely distributed plant in Tibet, and shows remarkable variations in stature, umbels, calyx, and corolla. Some of these are so marked in the dried specimens that it appears to be probable that more knowledge of the living plants and their relations will warrant segregation of forms within the type. As we know it at the present moment P. tibetica, Watt—if phyletically more nearly associated with the aggregate P. sibivica, Jacq. than with other species,—is a species easily diagnosed from P. szbirica, Jacq. by obvious char- acters, of which I have found the following never to fail, whether in herbarium specimens or living plants :—As anthesis proceeds the petals gradually reflex and become finally adpressed to the

side of the calyx, the consequence being that the long style, projected here far beyond the mouth of the corolla tube, stands up like a pin rising from the calyx, and in the short-styled flower the half-exserted anthers form a projecting fringe around the corolla tube mouth. This is most characteristic. In P. szbirica, Jacq. so far as I have seen it, the corolla lobes crumple up at the end of the tube without reflexing, and there is but slight protrusion of the style. There are other features of the bracts and the inflorescence which I think will prove to be additionally diagnostic, but it is too soon to write of them with conviction.

62 BALFOUR—NEW SPECIES OF PRIMULA.

N.W. China. Kansu, in Northern Peling. Alt. 10,000- 12,000 ft. Fenwick Owen. Raised from seed in April 1914 by R. W. Woodward, jun., Esq., of Arley Castle.

Mr. Woodward has been so kind as to present a living seedling plant of this species to the Royal Botanic Garden, Edinburgh. It has lived through the critical seasonal period of Primula life, and we may hope therefore to learn more of it when it flowers in another season.

t the Primula Conference in 1913 I gave some rough statistics for the purpose of showing the rapid increase during preceding years in the number of known species of Primula, and I predicted even more rapid addition in the near future. The fifty new species described in these pages fulfil the predic- tion, and I may add that descriptions of as many more will appear in early forthcoming numbers of these ‘“ Notes.’’ Most of the species here published we owe to recent exploration of N.W. China by Forrest, Kingdon Ward, Farrer, and Purdom, and of Eastern Himalaya by Cooper ; but a considerable number are an outcome of revision of the rich material gathered by previous collectors and now preserved in the public Herbaria at Kew, Calcutta, and Edinburgh. I have to thank the Director of Kew for the facilities I have had for examining the Kew collections. To Major Gage, Director of the Royal Botanic Garden, Calcutta, I am particularly indebted for his kindness in lending me for examination the unique series of specimens of Indian species belonging to the Calcutta Herbarium. Mr. W. W. Smith’s co-operation has brought to the diagnosis of Indian species his great knowledge of Indian Primulas de- rived from observation of the species in the field, and to Mr. W. G. Craib of Kew I am no less indebted for help and criticism.

The Two Rust Diseases of the Spruce. BY

A. W. BORTHWICK, D.Sc.,

Advisory Officer for Forestry to the Board of Agriculture for Scotland,

AND

MALCOLM WILSON, D-Sc., F.L.S., Lecturer in Mycology in the University of Edinburgh.

With Plate CXLIX.

- Chrysomyxa Rhododendri, De Bary. The Spruce Blister Rust, Rust of Rhododendrons.

Chrysomyxa Rhododendri was first recorded in Britain by D. A. Boyd in June 1913, who discovered the uredospore and teleutospore stages on Rhododendron hirsutum at Douglas Castle, Lanarkshire.

Shortly afterwards, in October 1913, material of the aecidial stage of the fungus on Picea excelsa was sent for identification to one of the writers from the south-west of Scotland, and its discovery was recorded in the Proceedings of the Botanical Society of Edinburgh in June 1914.*

The life-history of this species was first described in 1879 by De Bary,+ who showed that, the forms previously known as Aecidium abietinum and Uredo Rhododendri were stages in the development of one species to which he assigned the present name.

This species is found frequently in the Alps wherever the Alpine Rose (Rhododendron hirsutum and R. ferrugineum) occurs. The yellow clusters of uredospores are developed in September on the lower surface of the leaves and also on the bark of the

shoots of the previous year. The uredospores are oval in form and are produced in chains; they may further propagate the disease on the Rhododendron. Slightly later the development of the teleutospores commences, and in the following spring the sori appear as small dark red cushions on the lower surface of the leaf.

The teleutospores are formed closely together in groups covered by the epidermis, and each spore consists of a series of superimposed cells. A section of a mature sorus is shown in fig. 1. Immediately before germination the epidermis is ruptured and the terminal cell of the teleutospore, the only one capable of germination, gives rise to a four-celled pro- mycelium, each cell of which produces a sporidium. The sporidia are set free in June, and if they alight on the young leaves of the spruce may cause infection. A well-developed mycelium is produced in the leaf, and the infected area becomes yellow in colour. In some cases almost the whole of the leaf is infected, but generally the fungus is confined to certain zones and the remaining portions retain their normal greencolour. As a result of infection small yellow spermagonia are first produced, and these are soon followed by the aecidia. Each aecidial sorus is surrounded by a long white pseudoperidium which, in the early stages, completely encloses the spores. The aecidio- spores are arranged in chains and are produced from the base of the aecidium ; they are orange-yellow in colour. At maturity the pseudoperidium breaks down at its apex and allows the aecidiospores to escape as a powdery orange-yellow mass. Before dehiscence the pseudoperidium has the form of a cylinder terminated by a rounded cone and possesses a yellow tint due to the colour of the enclosed spores. After the spores are shed the form is that of an open cylinder and the pseudoperidium is perfectly white. The aecidiospores are distributed by the wind, and if they alight on the leaves of the Rhododendron are capable of producing infection.

The material of the aecidial stage of the fungus was obtained in October, some time after its maturity and the greater part of the spores had already been shed. An examination showed that in addition to the aecidia small yellow spermagonia are present. The number of aecidia present on a leaf varies.

Fig. 2 is from a photograph of a leaf bearing two pseudo- peridia ; several other aecidia were present, but the pseudo- peridia surrounding them had fallen away. The pseudoperidium ‘consists of a single layer of thick-walled pitted cells with strongly verrucose walls (see fig. 3, in which the upper cells are shown in surface view and the lower in optical section). The aecidio- spores are subglobose or ellipsoid, usually with a somewhat

flattened side, 20-24 x 20-23 mw in size. The wall is strongly verrucose and pitted except at the flattened portion; fig. shows a spore in surface view, and fig. 5 one in optical section. The peculiar flattening of the aecidiospore depends on its method of development. A number of rows of cells are produced in the young aecidium, and in each row only every alternate cell gives rise to a spore. The intermediate cells which do not produce spores remain thin-walled and at maturity become gelatinous and almost disappear. The flattened part of the wall of the aecidiospore is the portion which was originally in contact with the intermediate cell below it, and, in some cases, the shrivelled remains of this cell are still attached and may be seen as a black line when the aecidiospore is seen in optical section (fig. 5). In districts where the spruce does not occur it is probable that the fungus may exist through the winter in the form of hibernating uredospores, which, in the following spring, can infect the Rhododendron ; it appears therefore that the presence of the spruce is not essential to the continued existence of the fungus. The aecidial stage on the spruce, however, can only exist where the Rhododendron is present, as the infection of the needles is only brought about by the sporidia. Since this is the case, the removal of the Rhododendron will completely check the disease.

It appears, therefore, that the spread of the disease on the spruce will be limited in this country since Rhododendron hirsutum and R. ferrugineum, although frequent in parks and gardens, are not usually grown in plantations. The fungus has been found on R. dahuricum, but does not attack R. ponticum, R. catawbiense, and their hybrids which are so commonly grown.

The effect of the disease on the Rhododendron is not serious ; on the spruce the diseased needles fall in the summer of infection, and in severe cases the trees may be almost stripped of foliage.

Chrysomyxa abietis, Wallr. The Needle Rust of the Spruce.

Chrysomyxa abietis was first recorded in Scotland by Somer- ville,* from Durris near Aberdeen, and, writing in January 1915, 3 the same investigator stated that up to that time he had received no further reports of its occurrence. A quantity of the fungus was recently obtained from Aberdeenshire, and in view of the omission of this species from recent works on British Uredineae as well as its importance as a disease of the spruce, further in- quiries as to its distribution in Scotland have been made.

68 BoRTHWICK AND WILSON—Two Rust DISEASES OF SPRUCE.

Professor Trail has kindly forwarded the following informa- tion :—

“It is not more than six or seven years ago that I first observed Chrysomyxa abietis in Aberdeenshire, and it is probable that the fungus has only recently made its appearance in the north of Scotland. I have seen trees attacked by the disease in the Monymusk and Farland districts. The disease is now also very common in the spruce woods on the banks of the Findhorn, where it was first noted some three or four years ago by Mr. William Watt, Assistant Forester on the Moray estates. When the infected trees in this locality are standing singly and foliaged to the ground, only the leaves on the lower branches are as yet attacked.”’

Mr. P. Leslie, Lecturer in Forestry at the North of Scotland College of Agriculture, informs us that Chrysomyxa abietis is stated to be quite common on the Novar estate, Ross-shire. It is evident, therefore, that the disease is spreading to a con- siderable extent.

Chrysomyxa abietis, which is widely spread in Switzerland and Germany, is an autoecious species completing its life-history on the spruce. It differs from C. Rhododendyi in producing only one kind of spore, the teleutospore. The hibernating teleutospores germinate about May and produce sporidia which | infect the young leaves of the spruce. An abundant intercellular mycelium is developed in the tissue of the leaf which sends haustoria into the cell cavities. The hyphae contain numerous yellow oil-drops, and in consequence yellow bands appear on the leaf. Soon afterwards teleuto-sori are produced which take the form of elongated yellow cushions on both the under surfaces of the leaf (fig. 6). During the winter the sori are covered, but in the following spring the epidermis is ruptured and the teleutospores project as an orange-yellow mass (fig. 7). Each teleutospore is cylindrical and consists of 8-12 superposed cells of which only the terminal one produces a promycelium (fig. 8). At about the middle of May the sorus becomes brighter yellow and the promycelia grow out. Each produces four small spherical sporidia, which become easily detached and are distributed by the wind. When the sporidia have been shed, the sorus loses its bright colour and shortly afterwards the diseased leaf falls. On coming into contact with the young needles of the spruce the sporidium produces a germ tube which bores through the epidermis and so brings about infection.

It frequently happens that certain spruces in a wood remain © free from the disease, while others are badly attacked. This may be explained by the fact that infection of the young leaves only takes place at a certain stage in their development ; trees

BORTHWICK AND WILSON—Two Rust DISEASES OF SPRUCE. 69

which are in a backward condition when the sporidia are ripe are not infected, while at the same time others may have passed the susceptible stage and thus escape the disease.

As a result of the attack the infected leaves die and fall from the tree, and thus a considerable defoliation may take place. The disease, however, usually fails to maintain itself through a long series of years on any one tree and in consequence felling is not desirable.

In the last issue of the Quarterly Journal of Forestry,* which we have just received on going to press, Dr. Somerville states that on April 21st specimens of spruce branches badly attacked by Chrysomyxa abietis were sent to him by Mr. Neil MacGregor, Bridge of Dye, Banchory, Kincardineshire. The specimens _ were from trees about twenty years old which were planted under old larch and Scots pine, and were situated about seven miles from the nearest part of the Durris Woods, in which Dr. Somerville discovered the disease in IgII.

We desire to thank Professor Trail and Mr. P. Leslie, M.A., B.Sc., who have kindly supplied information as to the distribution of Chrysomyxa abtetis.

It does not range northward, and the flowering specimen was gathered from a strange outlying colony at the edge of subalpine coppice below Chago, in the Satanee Valley on 8th May. These magnificent thyrses appear before the leaves, which afterwards unfold to hide all trace of them: they suggest a glorified Veronica Hulkeana on a big scale, and have the most delicious scent of raspberry ice. Kansu, West China.” Farrer and Purdom. No. 44 in Herb. Edin.

This should prove a very decided acquisition to horticulture. The leaves are very beautiful, and with the ample inflorescences justify Mr. Farrer’s description of this plant as a noble bush. The foliage suggests to us an affinity with B. agathosma, Diels, but the relationship is not close.
