Dear Mr. Schweinfurth: 
I thank you for the list of names 
of the Ooeta Rican orchids that I find here upon returning 
from a brief vacation in southern Florida. The specimens 
also have arrived, and I am sending the names of all to 
Valerio, who, I know, will be much pleased to have them. 
He is making an earnest attempt to build up the herbarium 
there. He is a young man and, if some of his eccentricities 
to not interefere with his holding his position, he should 
be there for a long while, and accomplish something worth 
while. He has sent us probably 12,000 specimens so far, 
and they form an important collection for study of the Costa 
Rican flora. Several new collectors have begun work during: 
the past year, and I hope they may be able to get into some 
of the regions that still await ex jloration. 
I can assure you that so far as I personally am concerned 
your work of determining these orchids is deeply appreciated. 
Having so much work of the same nature to do myself, I know 
how much time is involved, and I judge that the time required 
for orchids is substantially more than in the case of the 
Costa Rican groups with which I have worked. 
Sincerely yours,
