This plant is certainly very closely related to Gentiana 
Piasezkii, Maxim., and it has been described as a new species 
with some hesitation. Of the characters enumerated in the 
differential diagnosis it seems probable that the shape of the 
stigmatic lobes will prove most definite.

The species, Gentiana tubiflora, Wall., was originally described 
from specimens collected in Nepal. It is not uncommon at 
considerable altitudes in the Central Himalayas and is recorded 
“ Sikkim, Nepal, Kumaon, Tihri-Garhwal and Western 
et.

A comparison of this species with Dracocephalum hetero- 
phyllum, Benth., has been given above, but the alliance is not 
close, differences being found in the habit, the leaves, and flowers, 
most especially in the calyx, which in our plant has a remarkably 
short, common tube only about 1 mm. in length. The calyx is 
perhaps more distinctly 2-lipped than that of any previous 
known species of the genus, and though there is little doubt that 
it should be placed in Briquet’s section Stenodracontes, it does
