Mr. Oakes .Ames, 
355 Commonwealth Avenue, 
Boston, Massachusetts• 
Dear Mr. Ames: 
Your letter of December 14 with regard to the new 
Pleurotballis from the Volcano of San Vincente is received. 
I shall ask Doctor Calderon to lock out for the plant and 
see if he can not obtain additional specimens of it. 
We are forwarding, by mail, a package containing 7 
specimens of orchids included in a shipment received for 
identification from the Guatemalan Department of Agriculture. 
We should be greatly obliged for your identifications of these 
when it may be convenient to send them. The specimens sent, 
which comprise all the material that we received, are so 
fragmentary that identifications may not be possible in all 
cases. They need not be returned to us. 
Have you ever bad any correspondence with Mr. Mariano 
Pacheco of Guatemala City? I understand that he is a dealer 
in orchids and has a small collection of them at his residence 
We have just received a letter from him in which he states 
that he is anxious to obtain publications upon the plants of 
tropical America, and offers to send in return for them plants 
especially orchids. We shall be glad to send him some pub¬ 
lications, but we do not have any use for living plants from 
Guatemala, and I doubt that he is prepared to send dried speci 
mens. Very likely you might be able to obtain somiething of 
interest from him, if you wish to write to him directly. I am 
sure he would be pleased to obtain your publications, but I 
should be inclined not to send them to him without a definite 
promise from him of orchid material, for the Latin Americans 
while very generous in their promises are too rarely given to 
fulfilling them. Mr. Pacheco’s address is Avenida Cand. 26, 
Guatemala City. 
Sincerely yours, 
Paul C. Standley 
Assistant gurator, 
Division of Plants.
