Dendrobium denudans is one of three very closely allied 
species, natives of the temperate regions of the Himalaya, 
which indicate the westernmost limit of the vast Asiatic 
genus to which they belong. Judging from dried 
specimens and drawings all three, namely, D. alpestre, 
Royle, D. erixflorum, Griff., and the plant here figured, 
are very variable in size, in the length of the raceme, and 
number of flowers, and in the size and coloration of the 
latter, from pure white, with a little purple on the lip, to 
a decided green. 
D. denudans was discovered by Dr. Wallich in Nepal in 
1821. It was introduced, probably from the Khasia Hills, 
into the Duke of Devonshire’s garden at Chatsworth by 
Mr. Gibson, when collecting in India for the Duke. It 
flowered there in 1838, and was described by Lindley 
as bearing a profusion of green and white nodding 
racemes. In 1844 Lindley again describes it, as a species 
most variable in size, but always to be distinguished by 
the loose membranous sheaths which persist on the stem 
after the leaves fall off; the sepals and petals elongate, 
pale, yellow-white, or greenish-white, lip green, whole- 
coloured.
