Eorth Easton, Mass* August 6 th, 1 y25 * 
My" dear Dr. Standley: 
I Deg to submit my report on 
three orchid specimens sent for determination, these 
"being the ones referred to in your Lie tter of July 
31 st. 
Calderon 1537...... Epidendrum difforme Jaotj. Material 
very poor. 
Calderon 1 583 ..... * Ponera striata Lindl. 
Calderon 1645 ...... Sobrailia sp. This specimen is 
without flowers. It may he S. maorantha 
Lindl. or S. xantholeuca Williams. If 
the former the flowers would he rose- 
purple, if the latter, the flowers would 
he cream-white or yellow. Perhaps Dr* 
Calderon can ascertain what the flower 
color was reported to he* Or, if com¬ 
plete specimens are available later, it 
will he simple to identify the material. 
Yours faithfully.
