his superb Dendrobium, considered the finest white-flowered species 
of all the genus, is widely dispersed throughout English India, on the 
is) Southern side of the Himalaya, from Nepaul to the Province of Assam ; 
it is to be found southwards as far as Tenasserim and the Andaman Islands. 
It not only grows on the trunks of trees, but also on the rock sides, where
