Dear Mr, Schweinfurth: 
Thank you very much for the list of 
Yucatan orchids included in your letter of July 7th. The 
information which you give will certainly be very help- 
full in correcting the previous list. 
I am expecting to go to this region 
this fall for collecting and I hope that it may be possi¬ 
ble to extend this list considerably. 
Sincerely yours, 
Paul C. Standley,
