My dear Mr. Powell: 
Two packages of specimens arrived this noon. I 
have examined the mounted set and now take this opportunity to re¬ 
port as I imagine you are always anxious to know what you have turn¬ 
ed up. 
273. Masdevallia regarding which I have already written an 
opinion. This additional material bothers me consider¬ 
ably. As you see this plant in vivo do you think it is 
the same as your 223, or do you regard it the same as 
your 70? Structurally it goes into il. panamensia . but it 
has an aura that soems to differentiate it. I am really 
puzzled to know just what to do with this plant. May I 
rely on you to study the two numbers critically for any 
differences that lead you to believe that two species 
are under consideration? 
279 This is excellent material of Pleurothallis Wggneri Johltr. 
280 apidendrum blsulcatum Ames sp. nov. This is near jfi. vleji 
Heichb. f., but quite distinct. I ha\'e yet to run it 
through the South American range before publishing the 
description. It is new to Central America. The specific 
name alludes to the the two tiny grooves in fron of the 
£81 basal oalli. 
281 Probably the same as 280. I think it is just a more ro¬ 
bust state. 3ut I intend to study it some more.
