A tall, robust Gentian, placed in the section Chondro- 
phyllum in the *Icones Plantarum” where it was first 
described, but falling under Pnewmonanthe in Clarke’s 
arrangement of the Indian species (in the “Flora of 
British India”) where the latter section is distinguished 
from the former by the reticulate testa of the seeds. Its 
nearest ally is G. robusta, King (l.c. t. 1439) which has 
narrower leaves, linear teeth on the margin of the calyx- 
tube, and along style. These two differ from all other 
Himalayan species (except G. stylophora which attains 
six feet) by their size and robustness. They both inhabit 
elevations of about 11,000 feet in a remote triangular 
corner of the interior Himalaya, bordering Tibet, between 
Sikkim and Bhotan, called Chumbi; a region remarkable 
for its dry climate, being cut off by lofty ranges from the 
southerly rain-bringing winds. Owing to its climate not 
a few plants unknown in Sikkim have been found jn 
Chumbi ; notably Pinus excelsa, and more may be expected 
when it shall be visited by Europeans, who have up to the
