ORCHIDACE# 
ovalia, obtusa, trinervia. Sepalum dorsale 5 mm. longum, circa 
2 mm. latum, valde convexum, oblongo-ellipticum, obtusum. 
Petala 5 mm. longa, linearia, uninervia. Labellum cum auriculis 
7 mm. longum, 4 mm. latum, antice utrinque in dentes duos 
fissum; lobus terminalis bifidus vel tridentatus dentibus lateral- 
ibus longioribus; auriculae 3.5 mm. longae, acutae vel obtusae, 
triangulares, elongatae; fovea margine superiore leviter semi- 
lunato-incrassata. Gynostemium breve. 
The type consists of a single plant preserved in the Herbarium 
of the Bureau of Science at Manila. The leaves may be more 
or less than four. The labellum indicates a wide range of vari- 
ation in the shape, length and position of the teeth. The two 
lateral teeth on each side of the tridentate or simply bifid mid- 
dle lobe are narrowly triangular in shape, about 1 mm. long. The 
middle lobe is variable, sometimes being deeply bifid. When it 
is tridentate the lateral teeth are much longer than the middle 
one. In the type the dried flowers are yellowish. The color of 
fresh flowers is not described in the collector’s notes.
