basi rotundatis et leviter cordatis, usque ad 24 cm longis; sti- 
pulis usque ad 3 em longis, late falcato-acinaciformibus, acu- 
minatis; spicis ¢ fasciculatis, sessilibus vel breviter pedunculatis, 
1 ad 2 cm longis, cylindraceis, floribus sessilibus, staminibus 2 
vel 3; inflorescentiis masculinis axillaribus, fasciculatis, floribus 
5-meris, racemose dispositis; ovario vestito. 
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 2mm long. Pistillate inflorescences axillary, fascicled, 
the flowers 5-merous, racemosely arranged, the rachis densely 
fulvous-pubescent, about 2.5 em 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
