TROPICAL AMERICAN ORCHIDS 
Mr. Rolfe was unable to identify the specimens and sug¬ 
gested that proposals regarding them be delayed until the Rei- 
chenbachian Herbarium should be unsealed. He feared that 
some of the ambiguous species described by Reichenbach 
might be conspecific with the Floridian species. In the 
preparation of an enumeration of the orchids of the United 
States and Canada it has been necessary to take up again 
the identity of the species. As I have been unable to ascribe 
it to any described species, I have proposed for it the name 
given above. [Fig. 2, X 2.]
