V.V. 
This plant forms a tuft of pseudo-bulbs, tolerably close 
together and cylindric in shape, barely larger at the base than 
at the apex. The flowers, of which each plant usually produces 
a number at once, are dull and inconspicuous. They are of @ 
putty-yellow, curiously ribbed on the outside. The lip is small, 
broad, and tbick, the apex decurved and the sides also deflexed ; 
it is fleshy and squared in outline, in colour of a dull pinkish 
red. The ovary ribs are elevated into sharp, waved keels.
