variable, and much more material is needed before it is possible to fix the limits of 

 these variations including the shape of the lobes, and the pubescence and glands of 

 the involucres. The geographical area occupied by C. Jacquernontii seems to be 

 confined to the western Himalaya, while C. ferox Wallich does not occur in Kash- 

 mir but extends to Sikkim. In China C. tibetica Eatalin and C. chinensis Franchet 

 occur within almost the same geographical region.
