Primula.'] LXXXVII. PRIMULACEJ;. (J. D. Hooker.) 483 



the genus those with the margins of the leaves revolute, and those with them de- 

 scribed as involute in vernation the first embraces all the Indian species but P. flori- 

 bunda, of which the vernation is very obscure and conduplicate. Under the first (A) 

 of the two primary divisions here proposed (these are purely artificial, and proposed 

 for convenience sake), all the species allied to P. sinensis (namely, 1, 2, 5, 7, 8) will 

 be found ; of the others, P. pulchra is closely allied to P. Kingii, P. reticulata to 

 P. sikkimensis, and P. Clarkei to P. petiolaris. The sections established under the 

 second division (B) are, I think, for the most part natural, and follow one another in 

 a fairly good sequence. The form of the top of the ovary, of the stigma, and of the 

 seeds, afford good characters ; but I have not been able to apply them sectionally. 



A. Leaves on long slender unwinged petioles, orbicular oblong or cordate, 

 margins revolute in vernation. (See P. petiolaris, sibirica, involucj-ata, and 

 tibetica in B). 



* Quite or nearly glabrous, mealy or not. 



1. P. rotundifolla, Watt, in Eoxb. Fl. 2nd. ed. Carey $ Wall. ii. ]8; 

 Cat. 605 ; more or less mealy, leaves l-4 in. diam. orbicular-cordate toothed 

 crenate or erose, umbels often superposed many-fld., bracts many subulate, corolla 

 purple, mouth annulate, limb flat, capsule oblong exserted. Duiby in DC. 

 Prodr. viii. 41 ; Don Prodr. 79. P. odontophylla, Wall. Cat. 7016. 



TEMPERATE HIMALAYA; from Kashmir, alt. 11,000 ft., to Sikkim, air. 12-13.000 ft. 



Buds densely clothed with sulphurous meal. Leaves membranous, sometimes 

 lobulate ; petiole 6-12 in. Scape as tall and inflorescence puberulous and mealy; 

 bracts many. Corolla-tube twice as long as the calyx ; limb flat, ^ J in. diam. ; 

 lobes obovate or obcordate. Ovary with a thickened lobulate crown ; stigma cuneate. 

 Capsule - in. Seeds pale, ~ in., irregularly ellipsoid, coarsely papillose. 



2. P. Crambeliana, Watt in Journ. Linn. Soc. Sot. ined. ; buds mealy, 

 leaves -1 in. diam. orbicular-cordate toothed, umbels few-fld., bracts 1-3 

 subulate, corolla purple, mouth annulate, lobes orbicular emarginate. 



SIKKIM HIMALAYA; Jongri, alt. 14,000 ft., Watt. 



A smaller plant, with much fewer and larger flowers, than P. rotundifolia, but I 

 have seen only four specimens from the one known locality. Leaves membranous ; 

 petiole not sheathed at the base as in P. pulchra, which this a good deal re- 

 sembles. Scape and inflorescence quite glabrous. Corolla limb concave, 1-1 in. 

 diam. Ovary and stigma as in P. rotundifolia. Fruit unknown. 



3. P. pulchra, Watt in Journ. Linn. Soc. Sot. ined.] glabrous, not 

 mealy, ba.sal sheaths long membranous, leaves oblong or ovate-oblong, glaucous 

 beneath, base rounded or cordate, tip rounded, margin waved, scape short, 

 bracts filiform or subulate membranous, flowers 2-10 loosely umbelled, corolla 

 purple, tube funnel-shaped, mouth obscurely annulate, lobes broad obcordate. 



SIKKIM HIMALAYA ; Lachen, alt. 12-14,000 ft., J. D. H. ; Jongri. Watt. 



Sheaths l-l|in. long, embracing the petioles. Leaves few, blade 1-l^in., midrib stout, 

 nerves few; petiole 1-1^ in. Scape about equalling the petiole; bracts much 

 shorter and more slender than the very unequal pedicels. Calyx \-^ in., terete. 

 Corolla very large for the size of the plant, |-1 in. diam. Ovary globose, subacute ; 

 stigma globose. Fruit unknown. 



4. P. reticulata, Wall, in Eoxb. Fl. Ind. ed. Carey fy Watt. ii. 21 ; Cat. 

 608 ; glabrous, slightly mealy or not, leaves very long-petioled oblong-sorda+e 

 obtuse crenate or doubly crenate reticulate glaucous beneath, scape very tall, 

 bracts large linear-oblong or lanceolate, base not produced, calyx-lobes short 

 acute recurved, corolla yellow, tube funnel-shaped slender much exserted,
