Kawsum: mountains east of Lake Kokonor, and on Upper 
Hoangho (Przewalski ex Bretschneider) ; Hurrun: Fang, 8000- 
9000 feet (4. Henry, 6798, 6798 A !). Mus. Brit.; Herb. Kew. 
Var. Prattii, Burkill. Amenti bracteg margine ciliatze : lobi 
spathulati. Pedunculus pubescens. 
SZECHUEN : Tachienlu, 13,500 feet (Pratt, 236 !). Mus. Brit. ; 
Herb. Kew. ; Mus. Paris. 
The type is found in the Himalaya, Western Tibet, and 
Afghanistan ; it is also presumedly found in Japan. T have seen 
no Japanese specimens which I could unhesitatingly refer to this 
Species ; but, so faras English Herbaria are concerned, better and 
more ripe material is desirable. A form approaching the variety 
Prattii occurs in Kumaon, where Wallich collected it; the cilia- 
tion is, however, somewhat less obvious.
