October 28, 1922, Pitter 10578 (type). 
This is the first Desmocelis reported from Venezuela, but it is probable that 
we also have D. villosa Naud., one form of which (D. villosa purpureo-violacea 
Cogn.) has been indicated by Karsten as growing in the plains of Villavicencio 
inColombia. The above-described species differs from the latter in its dis- 
tinctly petiolate and larger leaves, smaller flowers, longer filaments and 
anterior appendices of the connective, much shorter anthers and connectives, 
etc. The large and small anthers alternate regularly. The hairs on the upper 
face of the leaves issue from an elongated tubercle, brown in colour, immersed 
in, or adhering to, the parenchyma.
