fleshy; disc with a pair of subglobose fleshy calli at the 
base. Column about 6.5 mm. long at the back, strongly 
dilated above in front, with a denticulate rarely crenu- 
late clinandrium. 
This little plant appears to be allied to several Venezue- 
lan species, especially to Mpidendrum Armini Reichb. f. 
and to #. Moritz Reichb.f. However, it differs from 
both in having much shorter broader leaves and a dis- 
similar mid-lobe of the lip.
