‘Bhutan. Champa Pumthang. Alt. 12,000 ft. Herb in 
open turf in gaps of Abies forest.”” R. E. Cooper. No. 4000. 
1gth June 1915. 
This is another interesting new Primula from Bhutan, 
helping to bind the Himalayan with the West Chinese flora. 
P. Dianae belongs to the Amethystina Section, which is typi- 
cally represented in the Eastern Himalaya by the charming 
P. Kingit, Watt, and also by P. Gageana, Balf. fil. et W. W. Sm. 
From these Cooper’s plant is readily distinguished by the long 
petiolate leaves and the corolla not velvety puberulous. The 
Section is more numerously represented in China by P. amethy- 
stina, Franch., P. brevifolia, G. Forrest, P. leimonophila, Balf. 
fil., P. petrophyes, Balf. fil., and the small P. sélaensis, Franch. 
Cooper’s plant takes most after P. brevifolia, but from all these 
Chinese plants, as from the Indian, the long petioled leaves at 
once separate it.
