This little species is allied to D. Leonis, Reichb. f., which it 
resembles in form of leaf and flower, but it is always prostrate 
in habit, the stems lying flat on the tree trunks, emitting roots 
from their under side, and branching. The flowers are much 
smaller than those of D. Leon's, and have a vanilla scent. The 
lip bears at its end in the broadest part a small almost cubical 
callus.

T have little doubt as to the correctness of this identification, 
though I have not seen the type specimen. But, as Lindley’s 
description does not, in some respects, fit my specimen, I have 
given a fresh description.
