Dear Mr, Lankester: 
I am working over the Epidendrums for the 
orchid flora of Mexico and I came to Spidendrum equitantifo- 
llum.b In studying the representatives of that species out¬ 
side of Mexico I found that the Costa Bican material is de¬ 
cidedly different. Unfortunately on the twelve Costa Rican 
specimens na have, there are only two flowers (on collections 
made by you), I wonder if you would be kind enough to see if 
you can get rae a few fresh flowers in alcohol for *study? 
The specimens we have were taken from duly to March, 
-Vith my regards, I am, 
Sincerely, 
Louis 0. Willi a ass
