The abundant material—unfortunately none in fruit—of. this 
plant sent by Mr. R. E. Cooper has enabled me to make sure of 
the identification of the several specimens collected during the 
Thibetan Frontier Expedition which are cited above. The 
Thibetan specimens in the Calcutta herbarium are excellent 
but few in number, and I hesitated about dissecting any of them, 
but Cooper’s specimens, which are without doubt the same 
plant, make this unnecessary. The Thibetan plants are labelled 
P. farinosa var. caucasica, Regel.
