Gamble gives the flowering season as August, and I first 
found it in flower in Sikkim late in July, whereas Mr. 
Gumbleton’s plant flowered in June, which and the climate 
of southern Ireland may account for the paleness of the 
colour. On the other hand, the flowers of Mr. Gumbleton's 
plants are rather larger than in any of my Sikkim 
specimens, which averaged little more than an inch in 
breadth of limb. : 
B. Colvilei is a native of the temperate regions of both 
the outer and inner ranges of the Sikkim Himalaya, at from 
10,000 to 12,000 ft. elevation. It bears the name of my 
late friend, the Right Hon. Sir James Colvile, F.R.S., who 
at the time of its discovery was Puisne Judge of the 
Supreme Court of Calcutta, and President of the Bengal 
Asiatic Society. — ;
