TROPICAL AMERICAN ORCHIDS 
Panama, On trail from Colon, C. W. Powell 338, 1923. 
Sepals and petals olive green, labellum white. Flowering in 
September. Sea level. (Type in Herb. Ames No. 27041.) 
Epidendrum lacustreLi’nd/. Fob Orch. Epidendrum 
(1853) 50; Reichb. f. in Walp. Ann. 6 (1862) 369. 
Epidendrum leucochilum Lind/. Orch. Linden. (1846) 
8, non Klotzsch. 
A specimen collected by Maxon in Nicaragua appears 
to represent this rare species which was originally discovered 
in Venezuela by Linden. Unless there are subtle differences 
between them which are evanescent in dried material, I do 
not doubt that the Venezuelan and Nicaraguan plants are 
identical. Lindley’s type consists simply of the inflorescence 
and the spathaceous bracts which subtend it, but the 
structure of the flowers is well exhibited in the dried specimen, 
and the outline of the labellum is clear in a sketch prepared 
by Lindley for an herbarium record. Epidendrum lacustre 
has not been reported heretofore as a native of Central 
America. The extension of range represented by Maxon’s 
Nicaraguan specimens is highly interesting, as the species 
up to the present time was known only from Venezuela, and 
is not one of those common species which range widely 
through the American tropics. That it should not have 
been reported from the country intervening between 
Nicaragua and Venezuela is probably the result of in¬ 
sufficient exploration rather than a peculiarity of dis¬ 
tribution.
