linear or lanceolate acuminate, peduncle long or short, flowers umbelled or 
corymbose, corolla glabrous, corona variable, follicles long flattened, seeds 
narrowly ob'ong. Dene. in DC. Prodr. viii. 547. C. longifolium, Martens ;

WESTERN TIBET, alt. 11-13000 ft., Thomson &c.—DisrurB. Afghanistan, Central 
and Western Asia. Mediterranean region to Spain. 
Leaves 1—5 in. long, very variable in width and in the size and spread of the basal 
lobes which are rounded at the tip and sometimes 1j in. long; petiole 1-12 in. 
Peduncle equalling or exceeding the petiole, pedicels pubescent. Sepals ovate, usually 
pubescent. Corolla 3-3 in. diam. ; segments ovate-oblong. Corona sometimes quite 
simple and cleft deeply into triangular lanceolate erect or spreading simple lobes, 
sometimes cupular and 5-lobed or with 2-5 subulate lobes, and furnished within wi.h 
a tongue-shaped process. Anthers sessile, or stalked by the column of filaments. 
Follicles quite unlike those of its congeners, 4—6 in. long, 4—4 in. diam., thinly coria- 
ceous, straight or slightly curved, somewhat compressed, hardly turgid, narrowed to 
a slender point. Seeds i in. long flat. 
2741012. €. Heydei, Hook. f.; twining, nearly glabrous, leaves lanceolate 
acuminate deeply cordate the lobes incurved often overlapping, sinus long 
narrow, peduncle slender, flowers corymbose, corolla glabrous, corona campanu- 
late, mouth with 5 long subulate exserted processes each with a short process 
at its inner base. 
Western TisET; Ladak, between Saspo and Kala-tse, Heyde. 
I have seen only Heyde's specimens, which differ entirely from C. acutum in the 
long incurved basal lobes of the leaf and the long teeth of the corona projecting 
beyond the corolla. 
13. C. Dalhousie, Wight Contrib. 55; twining, nearly glabrous, leaves 
elongate linear-lanceolate acuminate base cordate, lobes rounded, peduncles

WESTERN TEMPERATE HIMALAYA, from Sirmore to Kumaon, alt. 5-7000 ft. 
Stem slender, with sometimes a line of hairs. Leaves 3-7 by 4-1 in., membranous, 
basal lobes short rounded pointing backwards, sinus open, nerves very oblique; 
petiole 1-2 in. Peduncles shorter than the petioles ; pedicels slender, glabrous or 
puberulous. Flowers} in. diam., pale green. Sepals ovate. Corona equalling the 
corolla. 
tt Corolla pubescent within.
