rete, rugose when dry, the ultimate ones about 5 mm in diameter, 
the very tips of the branchlets sparingly ferruginous-pubescent. 
Leaves subcoriaceous, oblong to oblong-elliptic, 8 to 22 cm long, 
4 to 10 cm wide, entire, the apex shortly blunt-acuminate, the 
base broadly and abruptly rounded and rather deeply cordate; 
lateral nerves 8 to 12 on each side of the midrib, prominent, 
obscurely anastomosing, sparingly bearded on the axils on the 
lower surface; petioles 4 to 7 cm long. Staminate inflorescences 
axillary, solitary, narrowly paniculate, about 12 cm long, the 
branches few, the lower ones 2 cm long or less, 2- or 3-flowered, 
the upper ones small and 1-flowered, the pedicels 1.5 to 2 cm long, 
slender. Staminate flowers 4-merous, the buds ovoid, about 7 
to 8 mm long, the calyx glabrous externally except at the edges 
of the valvate lobes, the lobes broad, acute, irregular, apparently. 
free at maturity, inside densely villous. Anthers many in a glo- 
bose head.

Ramos & Pascasio, April 23, 1919, in forests at low altitudes. 
A very characteristic species, not closely related to any other 
one known to me, readily distinguished by its being nearly gla- 
brous and by its oblong to oblong-elliptic, glabrous leaves which 
are broadly rounded and rather deeply cordate at the base.
