tip, about 5.5 mm. high including the wing, prolonged 
into a prominent curved foot. 
Among the South American species, this plant recalls 
Pleurothallis rubens Lind|., but has a dissimilar lip. It 
appears to be more closely allied to the Central Ameri- 
ean P. dolichopus Schitr., but is unique in having an 
excised lip.

Restrepia ecuadorensis Rolfe in Kew Bull. (1892) 188, 
non Pleurothallis ecuadorensis Schltr. 
Plant rather small, epiphytic, with a creeping rhizome. 
Stems approximate, slender, several-jointed, about 4-10 
em. high, entirely or mostly concealed by several (up to 
7) sheaths which are loose, tubular, scarious and finely 
red-purple maculate (the upper ones maculate only at 
their base). Leaf solitary, erect, oblong-elliptic to oval, 
obtuse or acute, cuneate at the sessile base, up to 6 cm. 
long and 2.9 cm. wide. Inflorescences fascicled, one to 
several, 1-flowered, issuing from the uppermost sheath 
just below the leaf, with the pedicel about 5 cm. long. 
Flower rather large for the genus, bilabiate, membrana- 
ceous. Dorsal sepal linear-lanceolate, about 2.2 cm. long, 
from a concave oblong-lanceolate lower portion gradually 
narrowed to a filiform apex which is clavate-thickened 
near the tip. Lateral sepals connate into an elliptic-oblong 
bidentate lamina which is subequally long with the dor- 
sal sepal but more than twice as wide. Petals similar to 
the dorsal sepal but much smaller, the oblong-lanceolate 
lower portion sometimes with a more or less distinct ap- 
pressed tooth. Lip about 9 mm. long, abruptly dilated 
from a small claw into a relatively broad suborbicular
