32 (81.) /'• obtusifolia, Royle ; Kunawar, Kumaon, Sikkim, and Bhutan. 



It is by no means certain that we have correctly identified P. obtusifolia, Royle, 

 and possibly two or more very distinct plants have been placed under it : — 



Yar. Roylei, Fl, Brit. Ind., Sundakfu, Sikkim, a purple-flowered plant at 10- 

 1-2,000 feet, and a yellow condition at Yangpung at 15,000 feet. But if this be correct 

 it is carious that while the purple-flowered forms have a strong metallic smell that 

 causes beadache if much inhaled, the yellow states have a soft delicate odour and are 

 much like P. sikk'nnensis and /'. 'prolifera. It is often seen with solitary axillary 

 flowers and with or without umbellate scapes on the same root. 



88. /'. Tanmm, King; Sikkim, 11,000 feet. (This is the plant to which I gave the 

 MS. name of P. Balfouri and issued specimens under that name before I knew of 

 its having been described : it seems also to be P. obtusifolia, var. Griffitliii of the 

 PI, Brit. Ind. Flowers pale lavender-blue.) 



34 (35). P. Kingii, Watt ; Sikkim. (Flowers dark purple or claret-coloured ; fruits 

 globose.) 



35 (34). P. Gamniieano, King; Sikkim, 14,000 feet; also Yatung, Tibet. (Is possibly 

 only a form of P. Kincjii.) 



:{(; (.'57). P. Dickieana, Watt; Sikkim, Lachen, 10-13,000 feet. (Flowers yellow, 

 pubescent, not perfumed.) 



37 (30). P. Pantlingii, King; Sikkim. (Probably = P. Dickieana.) 



38. P. Elwesiana, King ; Sikkim, 12,000 feet. (Flowers large, solitary, purple, softly 

 pubescent.) 



."{0. ]'. tcnclla. King; Chumbi Yalley, Sikkim, 13,000 feet. (Flowers solitary, large, 

 bluish-white, glabrous ; bract outside the calyx, and flower thus sessile.) 



Section 5 : Petiolaris (fig. 73). — Leaves, originally spathulate but 

 becoming ovate, elliptic to rotund, and more or less cordate, deeply and 

 sharply serrate or lobed at least on upper half, suddenly constricted into 

 a distinct petiole (which in the early foliage may be broadly winged), 

 usually mealy, especially the scales, certain species quite glabrous, others 

 puberulous or even tomentose. Inflorescence solitary or few-flowered 

 and umbellate ; scape as long as the leaves or a little longer. Corolla 

 tube most frequently not much longer than the calyx, lobes emarginate or 

 toothed. Bracts forming a 1-seriate involucre, but never thickened nor 

 gibbous below. 



* North- West Himalayan Forms. 



f Leaves ghtbrous, spathulate to ovate rotund, slicatlis often prominent (except 

 P. Stirtoniana, which has the young leaves sometimes glandularly puberulous). 



40 (43, 44, 45). P. petiolaris, Wall. (fig. 73, a and c) ; Simla to Kumaon (var. 

 sca/ngcra in Bhutan), Sikkim and Yatung, Tibet, var. Edgeworthii has rotund leaves 

 on long petioles. 8-10,000 feet. 



41 (51). P. Clarkei, Watt; Kashmir, 7,000 feet, 

 42. P. reptans, Hook. f. ; Kashmir, 15,000 feet. 



** Central and Eastern Himalayan Forms. 



48 (40). P. nana. Wall. ; Sikkim. 11-13,000 feet. (A dwarf plant with flowers very 

 small and leaves thin in texture and erose, otherwise P. petiolaris ; it flowers late in 

 autumn.) 



44 (40). P. Stirtoniana, Watt (fig. 73, b); Sikkim, Kanglanamo, 14 16,000 feet. 

 46 (40). P. UooLeri, Watt; Sikkim, 12.000 feet. 



46 (47). P. Dysriana, Bp, QOV.J Sikkim, Nepal, 13,000 feet. (Collected by Mr. 

 II artless.) 



•17 (46). t'. I'lilchra, W»tt; Sikkim, Jongri, 12-14,000 feet.
