Bletia Greenmaniana is superficially similar to B. re- 
flexa Lindl. It is, however, distinguished from all of the 
species known to me by its entire or, at most, somewhat 
undulate lip. 
Dr. J. M. Greenman indicated, many years ago, that 
the two specimens cited above were different from any- 
thing then known to him. They still seem to be unde- 
scribed, so it is with pleasure that the species is named 
for Dr. Greenman.
