would gladly have named after the collector who sent it to them. 
It seems however unquestionably specifically the same as D. hete- 
rocarpum, and as a variety of that we here give it. All the 
varieties are worthy of cultivation. 
For the description we must refer to that of the original 
Wallichian species (Tas. 4708) of the present work; the chief 
differences may be mentioned in few words: the stems are more 
slender, not so clavate, and the jovnés are less tumid; the “ip 
is for the most part pure white, the base only suffused with 
yellow, and the middle lobe of the lip, instead of having the 
whole disc of a deep golden sanguineous stain, has two dark 
sanguineons spots confined to its base.
