15,500 ft. July 1913.” F. Kingdon Ward. No. 812. (Mixed 
with P. Elwesit, Hook f. and P. praeruptorum, Bonati.) 
A plant having some affinities with the species of the series of 
Robustae of Prain in view of the staminal insertion towards the 
lower third of the tube of the corolla. It is separated however 
from all the species of this group by its hood furnished with a 
very developed crest and its beak not bifid. It has also affinities 
with the group of the Oxycarpae, among which its nearest rela- 
tive appears to be P. tibetica, Franch. It differs from the latter 
by its robust appearance, its flowers with long upright peduncles 
and by its larger corolla whose tube does not exceed the calyx. 
Its true position appears to be i in the group of the Oliganthae of 
Prain.
