ORCHIDACE.E 



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, acutaevel 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.
