Au ally of C. tomentosa, Lindl, like which it has the minute 
black tomentum, though much more sparingly on the pedicel. 
The bracts are very much shorter, the leaves and bulbs quite 
different in form, and the five ridges on the lip are entire and 
not broken up into truncate processes as in that species. 
It flowers in July.

A handsome and free-flowering species, remarkable for the 
thick conic smooth bulbs hardly at all grooved. The lip has 
broad blunt lateral lobes, the terminal one being rather long 
and oblong till the apex, where it rather suddenly enlarges into 
an almost reniform blade. The base is chrome yellow except 
between the two keels; the end is white with a sienua brown 
centre. The intermediate keel is very obscure, hardly to be 
seen.
