NEW OR NOTEWORTHY ORCHIDS 
subquadrate-ovate, 3-lobed, about 2.7 mm. long, nearly 2 
mm. wide across the side lobes, rounded-cuneate at base, 
abruptly truncate in front with a trilobulate apex; lateral 
lobes minute, suborbicular, fleshy. Disc 3-nerved, a pair of 
fleshy keels originating near the center of the lateral lobes 
and converging slightly toward the middle. Column stout, 
about 2 mm. long, slightly arcuate. Anther semiglobose.

This is the second representative of its genus to be 
recorded from Central America. Octomeria Valerioi is about 
twice as large as 0. costaricensis Schltr., and has much smaller 
flowers and very dissimilar lip. 
The description was made from dried specimens.
