XIV. 4 Merrill: Noteworthy Philippine Plants, XV 389 
A scandent shrub, the younger parts, petioles, and leaves on 
the costa above and on the costa, nerves, and reticulations 
beneath more or less ferruginous-pubescent. Branches terete, 
slender, very dark-brown, somewhat rugose. Leaves obovate 
to elliptic, subcoriaceous, 14 to 20 cm long, 8 to 12 cm wide, base 
broadly rounded, distinctly cordate, sometimes slightly inequi- 
lateral, apex rounded, truncate, or shortly and obscurely apl- 
culate, the upper surface olivaceous, shining, glabrous except 
the midrib, the lower surface brown, at times slightly glaucous ; 
lateral nerves about 13 on each side of the midrib, very prom- 
inent on the lower surface, straight or slightly curved, anas- 
tomosing near the margins, the primaiy reticulations subparallel, 
prominent; petioles stout, about 4 mm long, more or less pu- 
bescent, ultimately nearly glabrous. Infructescences axillary, 
the peduncles 2.5 to 3 cm long, dark-brown, ultimately glabrous, 
each bearing 20 to 25 subglobose to ovoid-globose fruits, the 
infructescences rather dense, globose, about 3 cm in diameter; 
fruits red when mature, acid, about 8 mm in diameter, spar- 
ingly pubescent, apiculate, dark-brown when dry, their pedicels 
about 8 mm long.

River, For. Bur. 26360 Mabesa, in forests, altitude 400 to 500 
meters. 
The alliance of this species is with Oxymitra obtusifolia Elm. 
and O. longiflora Merr., from which it is distinguished by its 
much broader leaves and nearly globose fruits.

oblongis ad oblongo-lanceolatis, usque ad 11 cm longis, chartaceis, 
acutis vel acuminatis, basi angustatis, leviter inaequilateralibus

carpellis circiter 5. 
An erect shrub, glabrous, except the young branchlets and 
flowers, the branches slender, terete, nearly black when dry, 
sparingly lenticellate. Leaves oblong to oblong-lanceolate, char-
