passing the pedicellate ovary, the lower ones 1.9—2.7 cm. 
long. Flowers rather small for the genus, non-resupinate 
in natural position (i.e. with the lip uppermost). Dorsal 
sepal linear-lanceolate, long-attenuate with conduplicate 
upper portion, about 3.7 cm. long and 5 mm. wide be- 
low. Lateral sepals similar but apparently a little longer 
and narrower (sometimes slightly broader), about 4.3 em. 
long and 4 mm. wide. Petals obliquely and narrowly 
lanceolate, long-attenuate above with conduplicate mar- 
gins, about 3.8 cm. long and 6 mm. wide below. Lip 
ovate or suborbicular-ovate, with the lobulate anterior 
margins terminating abruptly in a more or less elongate 
triangular or linear-triangular mucro, subcordate at base, 
about 1.5—2.1 em. long and 1.2-1.5 em. wide near the 
base; disc at the base just in front of the column with a 
pair of short approximate fleshy keels which are deeply 
constricted in front forming a pair of conical complanate 
teeth. Column very short and stout, wingless, about 8 
mm. high at the back. 
This species is extremely variable both vegetatively 
and florally. The measurements of the most complete 
specimen, which has been taken as the type, are uni- 
formly somewhat smaller than those of other collections. 
Brassia Allenii seems to be related to the Venezuelan 
Brassia glumacea Lindl., but differs in having a much 
stouter habit, in having the racemes markedly shorter 
than the leaves and in its apparently dissimilar lip. 
This concept was first considered as new and was 
named by Dr. Louis O. Williams, but has remained un- 
described until this time.
