TROPICAL AMERICAN ORCHIDS 
labellum blackish red like dried blood. (Type in Herb. Ames 
No. 26908.) 
Maxillaria maleolens Schlir. in Fedde Report. Bei- 
hefte 19 (1923) 233. 
Two plants from widely separated localities are referred 
to this species. Both plants show sepals which are ovate- 
oblong rather than narrowly oblong, and in this respect seem 
to resemble Maxillaria elatior Reichb. f. Both plants, more¬ 
over, have slightly smaller flowers (sepals about 2.1 instead 
of 2.4 cm. long, labellum 1.85-1.90 cm. long instead of 2.3 
cm. long) than those of the type. 
The Honduranian plant, which is said to be very com¬ 
mon where it was collected, appears to be a good match for 
the type of M. maleolens. 
The Panamanian plant shows considerable variation 
from the Honduranian plant, although vegetatively similar. 
It is apparently a lower plant with somewhat more fleshy 
leaves. The leaves are lanceolate-oblong rather than lorate, 
and are shorter and broader than in the typical plant (up to 
32.5 cm. long and 6.4 cm. wide). The chief difference is in 
the labellum, which is only lightly trilobed and is bright deep 
purple rather than yellow.
