concepts formerly accommodated in the genus Cunuria, 
whereas a tendency towards some form of pilosity on the 
under surface of the leaf was in evidence in most of the 
species hitherto included in Micrandra. The concept de- 
scribed by Croizat as Cunuria Gleasoniana has a thick, 
soft indument on the entire under surface of the leaf. 
This character, alone, would have suggested that the 
concept should represent a Micrandra.
