integerrima. Labellum pandurata, ad apicem bilobum, lobi ro- 
tundi. Ovarium hispidulum. 
Plants caulescent, similar to Oberonia mindorensis Ames, but 
different in the lobing of the lip, different petals and shorter 
pedicels. From base to tip of uppermost leaf, between 1 and 2 
dm tall. Leaves imbricating, ensiform, about 4 cm long, free 
portion spreading, somewhat recurved, 1 to 4 cm long, about 1 
cm deep where it forms an angle with the stem. Peduncle long, 
slender, about 1 dm long, about 4 mm through when the flowers 
are expanding. Bracts linear-lanceolate, aristate, equaling or 
slightly exceeding the flowers. Flowers greenish, approximate. 
Lateral sepals ovate, 0.75 mm long. Upper sepal similar to the 
laterals and about equal to them in size. Petals entire, ovate, 
obtuse, about 0.5 mm long. Labellum pandurate, 1 mm long, 
nearly 1 mm wide across the tip, margin entire, deeply retuse at
