Western HniAiAYA ; from Kashmir to Kumaon, alt. 6-9000 ft. 



Stem 1-4 ft., from glabrous to hispid with long spreading hairs, simple or branched. 

 Leaves so variable that it is difficult to arrange their forms under any system ; 1 {allia- 

 ricefolia), leaves entire, cordate or ovate or oblong, with the base truncate or cordate 

 obtuse or acute, petiole simple slender aurieled at the base ; 2 (raphanifolia), leaves 

 more or less pinnatifid with a terminal ovate lanceolate or deltoid acute terminal lobe 

 to which the leaf is sometimes reduced, petiole broadly winged dilated or not at the 

 base ; 3, leaves orbicular or broadly oblong, palmately 3-lobed, lobes cut and toothed, 

 petiole simple or toothed (when the leaf becomes pinnatifid). Heads ^— | in. ; outer 

 invol. bracts J-^ the length of the inner. Achenes J— J in., narrow, compressed, slightly ^ 

 contracted at the tip ; pappus scanty, brittle, white or pale brownish. 



3. P. violaefolia, Bene, in Sot. Jacq. Voy. 100, 1. 108 ; stem veiy slender 

 simple quite glabrous or with soft hairs at the top of the petiole, leaves long- 

 petioled ovate-cordate deltoid or hastate tip and auricles obtuse or acute entire 

 or obscurely sinuate-toothed glaucous beneath, petiole simple or winged or , 

 dilated at the base, heads racemose or subpaniculate narrow pendulous long- 

 peduncled 5-8-fLd., achenes ellipsoid shorter than the white pappus. Lactuca 

 violaefolia, Clarke Comp. Ind. 269. 



Westeen Himalaya; from Kashmir to Kumaon, alt. 9-12,000 ft. 



A small very slender species, a foot high, simple or sparingly branched. Leaves 

 1-2 in. long and broad ; petiole of the lower 3-8 in., simple or dilated at the base, 

 sometimes into a foliaceous orbicular toothed auricle, rarely with a pair of oblong 

 pinnules below the blade, nerves radiating from the tip of the petiole. Heads few, 

 subsolitary, pendulous ; invol. bracts ^ in., outer very small, inner linear obtuse. 

 Achenes ^ in., contracted at both ends, but not beaked. 



4. P. Kookeri, Clarke mss. ; stem simple or branched, glabrous except 

 the petiole and leaf-nerves beneath which are often setose, leaves hastate or 

 cordate obtuse quite entire rarely sinuate uppermost ovate or oblong, petiole not 

 longer than the blade with a broad ^-amplexicaul wing dilated downwards and 

 aiiricled at the base, heads -S-G-fld. racemose or panieled nan'ow pendulous, 

 peduncle long, achenes narrowly elliptic compressed contracted towards both 

 ends about equalling the white pappus. P. alata", Jfei-b. Hooh.f. ^ T. ; Clarlie

Khasia Mrs. ; in marshy places, alt. 4-6000 ft. Mahtaban Mrs. ; dry hills, alt. 

 5-6000 ft., Kurs. 



Stem 1-3 ft, quite glabrous, simple and slender or stout and much branched. 

 Leaves 1-2 in. long and broad, basal lobes spreading or deflexed ; petiole with flexu- 

 ous hairs underneath and towards the top only, wing gradually narrowed to the 

 insertion of the leaf-blade or below it. Flowers blue purple. Achenes J in., broader 

 and darker than in P. violsfolia, from which this differs conspicuously in the short 

 petioles. — Clarke suggests the alteration of the name from alata, which should he re- 

 tained for the P. {Nahalus) alata. Hook, f., W. America. Clarke describes the achenes 

 as cylindric, but I find all to be flattened. I have seen no Martaban specimens. 



6. P. sikklmensis, Hook. f. ; quite glabrous, stem elongate very slender 

 flexuous branched, leaves very membranous quite entire with slender petioles 

 winged towards the base simple (not aurieled) deltoid with rounded tip and 

 lobes or with a pair of pinnules on the petiole, heads panieled solitary long- 

 peduneled pendulous 5-6-fld., achenes large fusiform compressed equalling the- 

 white pappus.
