15 cm long, 3 to 4 cm wide, castaneous when dry, subequally 
narrowed to the acuminate apex and the acute base, the upper 
surface shining, glabrous, the lower paler, with short, rather 
scattered hairs over the entire surface; lateral nerves 10 to 12 on 
each side of the midrib, rather prominent on the lower surface; 
petioles pubescent, 1.5 to 2 cm long; stipules deciduous. Panicles 
densely ferruginous-pubescent, in fruit 5 to 7 cm long, shortly 
peduncled or branched from the base, the branches 3 to 5, op- 
posite, spreading, the fruits sessile at the apices of the primary 
branches, two or more fruits on each branch. Fruits red when 
fresh, when dry dark brown, narrowly obovoid, about 8 mm 
long, not at all sulcate, the upper part more or less ferruginous- 
pubescent. Seeds plano-convex, the albumen not at all 
ruminate.

This species is characterized by its brown indumentum, its oblong leaves, 
and its narrowly obovoid fruits, which are sessile and somewhat fascicled 
at the tips of the primary branches of the infructescences. It does not 
appear to be closely allied to any other described Philippine form.

Frutex scandens, glaber, ramis ramulisque teretibus, griseis 
vel brunneis; foliis chartaceis, oblongis vel oblongo-ovatis, usque 
ad 10 cm longis, prominente tenuiter acuminatis, basi acutis, 
supra olivaceis, subtus pallidis, nitidis, nervis utrinque 8 vel 9,

A scandent, entirely glabrous shrub, the branches and branch- 
lets terete, brown or grayish, smooth, the internodes 3 to 
8 cm long. Leaves chartaceous, oblong to oblong-ovate, 7 to 10 
cm long, 2.5 to 4 em wide, the apex prominently and slenderly 
acuminate, the base acute, the upper surface olivaceous, the 
lower much paler, shining; lateral nerves 8 or 9 on each side 
of the midrib, prominent on the lower surface, here brownish in 
contrast with the pale epidermis, curved, anastomosing, the reti- 
culations nearly obsolete; petioles 5 to 7 mm long; stipules deci- 
duous. Panicles up to 10 cm long, peduncled, lax, diffuse, the 
branches few, opposite, up to 4 cm in length. Fruit white when 
fresh, oblong-ellipsoid, about 5 mm long, brownish when dry
