Mr . Oakes Ames,

Boston, Massachusetts. 
Bear Mr. Ames: 
We are forwarding, by mail, a package containing 4 speci¬ 
mens of orchids collected in the State of Sinaloa, Mexico, and 
for which we should appreciate having your identifications 
when it may he convenient to send them. The specimens a.re 
duplicates and need not he returned to us. 
Thank you very much for the identifications of the Central 
American orchids just received. I was naturally much inter¬ 
ested in going over the list, and I regret that it is not a 
great deal more extensive. I have asked Boctor Cald.er<5n to 
make a special effort to take specimens of all the orchids 
that he may find upon his trips, and I am sure that he will do 
so. There must he many more species than those now known from 
the country. It is rather unfortunate that Schlechter is going 
ahead with the publication of the Central American orchids, 
hut perhaps after he has finished with the present lot of ma¬ 
terial he will not have anything further to work upon. If I 
can only get down to Costa Rica this year, I think it will not 
he very difficult, through personal contact, to make arrange¬ 
ments to have such orchids as are obtained by the collectors 
there forwarded to you for identification. I suspect, how¬ 
ever, that Mr. Jimenes is not doing very much in the way of 
collecting at the present time. 
Sincerely yours, 
Paul C. Standley
