lt appears to require as much heat and moisture as any of 
the Indian species, a circumstance which is explained by its 
inhabiting, when wild, the damp and sultry woods of Marta- 
ban. We believe it was originally distributed by the Horti- 
cultural Society; but it has hitherto flowered only in the 
collections of Mr. Harrison and Mr. Bateman, from both of 
whom we have received specimens. It blossoms in March 
and April. 
The lip of this species is remarkable for being much 
broader than long, and plaited in the middle in such a man- 
ner as to form a projection round the hollowed part which 
lies against the column; it is moreover more distinctly - 
articulated with the column than is usual in the genus. Its 
column has a fleshy reflexed appendix near its base. 
In the accompanying figure 1 represents the lip, viewed. 
from above : and 2 a section of the column and part of the 
lip, for the purpose of shewing at a the bed of the anther, 
at b the scale near the base of the column, at c the hairiness 
of the cavity of the lip, and at d the point of articulation 
between the lip and the column.
