Dear Dr. Robinson: 
I received your letter regarding the ideifttifi- 
cation of some of Professor Hitchcock's collection from 
British Guiana and shall be glad to help in it to the best 
of my ability. The Compositae which you ask me to name 
are not accessible at present here, as they are being 
mounted by outside parties. Mr. Standley tells me that 
they will probably be returned very soon, v/hen I shall be 
glad to naii'ie them, or I could name them now if you are in 
a hurry and care to send down your material of the numbers 
mentioned. I could also look after the Polygonaceae and 
Lauraceae. 
I have not had a chance to look over any of PrO' 
fessor Hitchcock's plants as they were all sent away to be 
miounted. 
Sincerely yours 
SFB/HT
