I do not propose to give a detailed list. The species of the Chola were collected in 
November 1849 in the vicinity of Laghep by Sir Joseph Hooker who enumerates 24 of 
them in Him. Journ., ii, 197. Further north near Fieunggong Mr. G. A. Gammie 
found all the Sikkim species with the exception oi Rhododendron nivale. It is as the 
latter points out — Gazetteer of Sikkim^ 1894, p, 107 — a remarkable specific concen* 
tration of the genus. As I was too late for the flowers.of the majoiity and much too 
early for seed, I did not devote any time to the genus though most of th© species were 
collected incidentally.
