ORCHIDACEA 
ovata, acuta. Sepalum dorsale simile. Petala oblonga vel sub- 
spathulata, 1 mm. longa, valde obtusa. Labellum circa 1 mm. 
longum, ad basim auriculato-cordatum, ad apicem rotundatum 
bilobatum, prope medium leviter constrictum vel angustatum. 
Columna simplex. 
In habit Oberonia leytensis suggests O. brevifolia Lindi. The 
sinus formed by the lobes of the lip is distinctly triangular. Five 
or more flowers make up the whorls of the arching or droop- 
ing raceme. O. mindorensis Ames has a very similar lip, but the 
habit of the plant is much more robust and the petals are linear.

Oberonia surigaensis is closely related to O. Wenzelii Ames, 
from which species it differs in part in the denticulation of the 
labellum. The teeth on the labellum of O. Wenzelii are confined 
to the margin of the basal half and are inconspicuously, if at all,
