Dear Mr. Ames: 
I am very glad indeed to know that you are will¬ 
ing to undertake the preparation of a list of the orchids of 
Costa Rica. The list will, I suspect, comprise a substantial 
portion of the completed work, since the family must be by 
far the largest one in the Costa Rican flora. Certainly the 
number of names to be considered must be extensive indeed. 
Probably it is better not to begin preparation of the 
account until I notify you that I have been successful in the 
printing of the first part. I am assured that it will proceed 
promptly, but of that I shall feel more certain when I see at 
least the proof. 
I expect to have the first portion of the mauscript, 
covering the families up to the Orchidace§e, completed in the 
near future, and shall send it to San Jose at once. The work 
of compilation has been relatively simple, since I already had 
most of the data in accessible form. 
Your work upon the North American Epidendrum species must 
be except ions, 11 y interesting. It will be most satisfactory 
to have something useful upon this large and difficult genus.
