It 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 h 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.
