 J. D. H. ; C. B. Clarice. 



Bootstock very long and stout, inclined. Leaves 2-18 in., linear- or obovate-ob- 

 Icng in outline, 1-2 J in. diam. across the broadest part; leaflets usually close and 

 often imbricate, J-IJ in., tip rounded, sessile, many-nerved, the alternate nerres 

 smaller, upper decurrent; petiole slender or stout; lower stipules membranous, upper 

 leafy toothed. Flowering stems with one or two leaves and a few-flowered irregular 

 corymb. Flowers J in. diam. ; pedicel elongating after flowering. Calyx silty, 

 lobes triangular acute ; bracteoles various, usu^ly toothed. Petals orbicular, yellow. 

 Stamens 20-30. Achenes few, ^ in. diam., four times as large as in any other Indian 

 species, dark brown ; receptacle low, villous. 



Vae. obscura ; covered with soft spreading hairs, not silvery, leaflets J in. broadly 

 oblong membranous less closely serrate softly hairy on both surfaces. — Kumaon at 

 Kalari, alt. 13,000 ft., Straoh. ^ Winterb. I have but one specimen, and though 

 I find no approach to pubescence on it, judging from the variation of P. splmdens, 

 Momiiana, and Leschenaultiana, it may well be referable to peduncularu, with which 

 it altogether agrees in habit, flower, and achenes. 



Vae. Clarkei ; dwarf, sparsely silky, not silvery, leaflets narrowly oblong. — Sikkim 

 at Yakla, alt. 14,000 ft., G. B. Clarke. 



20. P. leuconota, Don Prodr. 230 ; leaflets numerous (alternate some- 

 times minute) oblong obtuse sharply cloBely serrate clothed beneath with ap- 

 pressed shining silky hairs, flowering stems exceeding the leaves, flowers small

Bootstock very stout, sometimes 1 in. diam., inclined. Leaves 2-6 in., very numer- 

 ous, linear in outline or rather broader upwards ; leaflets close or sparse, J-| in.,.ses- 

 sile, glabrous or hairy above ; petiole with appressed hairs. Flowering stem erect or 

 ascending, with usually a leaf about the middle, and an imperfect whorl of reduced

Alpine Himalaya, from Garwhai,, alt. 10-14,700 ft. to Sikkim, alt. 15-18,000 ft. 



Very variable in habit and stature, forming at high elevations dense hard moss- 

 like tufts, strewed with golden flowers and Mrith the leaves so small and crowded as 

 with difficulty to be distinguished ; at lower elevations the leaves are 4-6^ by * in.
