20 (21). P. sibirica, Jacq. (fig. 71, b & c) ; Zanskar to Lahul, 13-15,000 feet. (A 

 smaller plant than P. involucrata, and with pink fiowers.)

21 (20). P. involucrata, Wall. ; Kashmir to Sikkim, 12-1-5,000 feet. 



22. P. tibctica, Watt ; Kumaon, Tibet, to Sikkim frontier, 15-17,000 feet. 



23. P. concinna, Watt. ; Sikkim, Tibetan passes, 15-17,000 feet. 



Section 4 : Purpurea (fig. 72). — Leaves thick, smooth, usually quite 

 glabrous, shining, more or less mealy on the under surface only or 

 all over, lanceolate to obovate-spathulate or even ovate- cordate, midrib 

 flattened, expanded and veined on the surface, extending along the blade 

 and forming a winged petiole, a large sheath or a stem-embracing scale, 

 leaves thus frequently borne on a distinct though winged petiole, mostly 

 serrulate on the top half of the blade. Inflorescence umbellate (that is to 

 say, attached to the common peduncle by pedicels), rarely solitary, more 

 often verticillate ; scape much longer than the leaves, swollen at the 

 extremity where the bracts form a more or less 1-seriate whorl, not 

 dilated below, but sometimes connate around the pedicels, occasionally 

 almost awl- shaped. Flowers yellow, purple, or blue, usually numerous, 

 but occasionally few or solitary. Corolla, tube expanding within the 

 throat, mouth obstructed, often annulate and lobes entire, or emarginate 

 or even crenate- serrate. 



* North- West Himalayan Forms. 



^Petals entire or only faintly emarginate : throat constricted but not annulated. 



24 (25). P. purpurea, Royle (fig. 72, a & b) ; Tibet, Lahul to Kumaon, 10-14,000 

 feet. (A very varialbe plant, but in its normal conditions quite distinct from P. 

 Stuartii ; fruit linear erect, exceeding the calyx ; flowers purple.) 



25 (24). P. Moorcroftiana, Wall. ; Kumaon and Kullu, 16,000 feet. (Fruit often one 

 inch long and more than twice the calyx ; flowers purple. Though a very different- 

 looking plant, is generally treated as a variety of purpurea.) (Fig. 72, c.) 



26. P. Inayati, Duthie ; Hazara, 4,500 feet. 



27. P. Stuartii, Wall. ; Tibet, Kashmir, and Chamba, also Sikkim, 12-14,000 feet. 

 (Fruit linear, about same length as the calyx ; flowers yellow, perfumed.) 



28. P. Traillii, sp. nov. ; Kullu, 16,000 feet. (Fruit globular, contained within the 

 calyx ; flowers pale blue.) 



** Central and Eastern Himalayan Forms. 



29. P. sikkimensis, Hook. ; Sikkim, in wet places, 11-15,000 feet. (Fruit globose ; 

 flowers lemon-yellow, delicately perfumed.) 



ft Petals distinctly emarginate and often crenate-serrate ; throat constricted and 

 obstructed with hairs, or furnished with a distinct annulus. 



30. P. prolifera, Wall. ; Khasia and Naga hills, in running water, 8,000 feet. 

 (Capsule globose : flowers yellow. Allied to, but distinct from, the Javan P. imperialis 

 and also P. sikkimensis and P. Traillii.) 



31 (32). P. elongata; Watt; Sikkim, 12-13,000 feet. (Closely allied to P. obtusifolia.)
