in British and Dutch Guiana, has recently been found 
in southern Venezuela.

In 1947, Baldwin and Schultes (loc. cit. 348) stated: 
‘The presence of a definite caruncle on the seed of this 
concept renders its inclusion in Cunuria untenable.’’ At 
that time, however, no transfer was made, even though 
it was recognized that all concepts which fell into the 
then apparently clear-cut genus Micrandra were carun- 
culate and that all which could be included in Cunwria 
were without this structure on the seed. Baldwin and 
Schultes, therefore, considered the presence or absence 
of acaruncle to be a character of value in distinguishing 
between the two genera, although former students of 
these groups had not mentioned the caruncle. Studies 
of additional material and the discovery of two new spe- 
cies, however, indicate that, like all other characters once 
used to separate Cunuria from Micrandra, the presence 
or absence of a caruncle is not stable. 
The presence of leaf pubescence was not known in the
