long, subtended by a cucullate acute bract which is 4 mm. 
long and tubular at the base. Flowers stramineous, con¬ 
spicuous. Lateral sepals 1.2 cm. long, 2 mm. wide above 
the base, narrowly triangular-lanceolate, terminating in a 
thickened subcaudate tip, 3-nerved, coherent, becoming free 
almost to the base. Dorsal sepal 1.2 cm. long, 1.5 mm. wide, 
narrowly lanceolate, 3-nerved, thickened toward the tip, 
subcaudate. Petals 6 mm. long, about 1 mm. wide near 
the base, linear-lanceolate, 1-nerved, thickened toward the 
apex, margin inconspicuously cellular-glandulose. Label- 
lum 2.5 mm. long, 1 mm. wide, oblong-lanceolate, acute, 
somewhat sigmoid when seen from the side, 3-nerved. Disc 
bicarinate near the base, the keels prominent and con¬ 
verging above; near the middle of the disc there is a thick¬ 
ened callus, obtusely triangular in outline, with its apex 
pointing toward the tip of the labellum. Column 2 mm. 
long, very fleshy, with a cucullate entire clinandrium. 
In habit this species suggests Pleurothallis repens Ames, 
but is CRiite distinct from it in the structure of the flower.
