_ This may possibly be the same as the next species, and I should have 
inclined so to consider it if the flowers had at all deserved the name of 
small, which they do not. It is also to be observed that Póppig describes 
the back sepal of his 4. parviflora as being fornicate, and the sepals as 
being half united to the back of the column, none of which characters are 
to be found in this species.

Of the original species of this genus I know nothing more than is to be 
found in Aublet. It does not however appear to differ from those I have 
examined, in anything more than its labellum being short and three lobed, 
to the latter of which characters there is an approach in C. parviflora. It is 
probable that Guayana contains other species, of which I have some indi- 
cations, but not sufficient for publication.
