A tree, glabrous or nearly glabrous except the inflorescences. 

 Branches stout, terete, dark colored when dry. Leaves oblong 

 to broadly oblong-lanceolate, 15 to 24 cm long, 5 to 6 cm wide, 

 coriaceous, shining, the base rounded, slightly cordate, the apex 

 prominently acuminate ; nerves about 14 on each side of the mid- 

 rib, very prominent beneath, curved-ascending, anastomosing, 

 the reticulations rather dense, distinct; petioles 1 to 1.5 cm long, 

 pubescent when young, ultimately glabrous ; stipules of the same 

 texture as the leaves, large and prominent, broadly falcate- 

 acinaciform, 2 to 3 cm long, the base broad and rounded, the 

 apex acuminate. Staminate inflorescences fasciculate, the flowers 

 arranged in dense cylindric spikes 1 to 2 cm long, which are 

 sessile or very shortly peduncled, their rachises pubescent. Ca- 

 lyx segments 3 or 4, slightly pubescent; stamens 2 or 3, their 

 filaments 2 mm long. Pistillate inflorescences axillary, fascicled, 

 the flowers 5-merous, racemosely arranged, the rachis densely 

 fulvous-pubescent, about 2.5 cm long; pedicels stout, about 1.5 

 mm long, each subtended by a small, ovate bracteole. Ovary 

 densely fulvous-pubescent. Fruit narrowly ovoid, glabrous, nar- 

 rowed upward, 1.5 cm long.

This species belongs in the group with Aporosa lunata Kurz, 

 A. benthamiana Hook, f., and A. falcifera Hook. f. together 

 with three Bornean species, A. hosei Merr., A. grandistipula 

 Merr., and A. euphlebia Merr. It seems to be closest, however, 

 to a Celebes form represented by Koorders 16801 and identified 

 by him, with doubt, as representing Antidesma auriculatum 

 Teysm. & Binn. I have not been able to locate any published
