106 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
The identification of the plants shows five species which are new 
to science. As far as can be ascertained, nine of the remaining species 
have never been recorded from Venezuela, and three have never be- 
fore been collected there, these being Phoradendron trinervinum, 
Corchorus pilobolus, and Marsdenia maculata. The remainder of 
the nine are in the collections that have not been reported upon.
