Western Europe, not uncommon. 



Var. grandiflora DC. ; puberulous, radical leaves more numerous, per- 

 sisting, cauline few; steuis stouter; segments of leaves obovate-oblong

Eastern Asia : Altai mountains ; Dahuria ; Northern Mongolia ; Kansu and

Rootstock 1-2 in. long, head 1/4 in. diam. ; stems 2-3 feet high except in var. 

 grandiflora where it is only 8-12 in.; radical leaves 5 in. long, pétioles 1 in., 

 segments 5-6-jugate, basai lobes usually very small subsessile, the rest petiol- 

 ulate 1 1 /z in. long. 3/4 in. wide, terminal lobe 2 */* i n - long, 2 in. wide; 

 cauline leaves similar but smaller, only 2-3 jugate, pétioles 1/4-1/2 in. ; pe- 

 duncle (a leafless branch) 3-5 in. long; cymes umbelliform 3-8-fld. ; sepals 1/4

 in. long bracts 1/8 in. long (in var. grandiflora 1/4 in.); capsule 2 in long (in 

 var. grandiflora only 3/4 in.).

 same species C. majus, C. laciniatum (quercifolium) and C. grandiflor- 

 um. These three forms are nevertheless very distinct and quite deserv- 

 ing of at least varietal rank. 



Regarding var. grandiflora, which is the most distinct of the three 

 and which in habit and appearance differs almost equally from both the 

 others, it must be admitted that so far as the spécimens from the area 

 which includes Soongaria, Dahuria and Mongolia are concerned, it
