Monoecious. Branches slender, striate-sulcate, glabrous or nearly so. 
Leaves lanceolate or oblong-lanceolate, 4 to 9 cm long, 1 to 3.5 cm wide, 
chartaceous, the base hastate, truncate, the basal lobes short, spreading

A species widely distributed in tlie pine region of Benguet Province, well 
characterized by its lanceolate, hastate, very scabrous leaves, and ovoid or oblong- 
ovoid rostrate fruits. Probably most closely allied to Melothria zeylanica Clarke, 
but very different from that species.
