rotundatis vel angustatis, semper auriculato-cordatis, apice 
abrupte acuminatis, nervis utrinque 17 ad 20, supra haud im- 
pressis, subtus valde perspicuis; petiolo 3 ad 4.5 cm longo; 
stipulis subcoriaceis, persistentibus, late acinaciformibus, usque 
ad 2.5 em longis et 1.5 cm latis; infructescentiis lateralibus, 
pedunculatis, solitariis, 2.5 ad 3.5 cm longis, fructibus plerum- 
que 2, longe pedicellatis, ovoideis, 1.5 ad 1.8 cm longis, 3-locel- 
latis, pericarpio fragile, 1:5 mm crasso. 
A glabrous tree about 6 m high. Leaves oblong, entire, 
firmly chartaceous to subcoriaceous, 20 to 30 cm long, 9 to 10 
cm wide, grayish olivaceous when dry, shining, the base rounded, 
_ sometimes distinctly narrowed, always auriculate-cordate, the 
apex rather abruptly acuminate; lateral nerves 17 to 20 on each 
side of the midrib, not impressed on the upper surface, very 
prominent on the lower surface, somewhat curved, arched-anas- 
tomosing, the reticulations distinct; petioles 3 to 4.5 cm long; 
stipules very broadly acinaciform, persistent, the same color and 
consistency as the leaves, up to 2.5 cm long and 1.5 cm wide, 
one end very broadly rounded, the other falcate-acuminate. 
Infructescences lateral, solitary, peduncled, each usually bear- 
ing two fruits, the peduncles up to 3.5 cm long, the pedicels up 
to 1 cm long. Fruits ovoid, yellow, 1.5 to 1.8 cm long, 3- 
celled, the pericarp rather brittle, about 1.5 mm thick. 
British North Borneo, Sandakan, Agama 579, August 22, 1918. 
In flat country of the Suanlamba River valley at low altitudes. 
This species belongs in the group with Aporosa benthamiana 
Hook. f, and A. lunata Benth. and is more closely allied to the 
former, from which it is distinguished especially by its fewer- 
nerved leaves, much toes petioles, and entirely different in- 
fructescences,

Arbor parva, glabra; foliis chartaceis, integris, nitidis, oblongo- 
ovatis ad elliptico-ovatis, 10 ad 17 cm longis, apice tenuiter 
acuminatis, nervis utrinque circiter 5, perspicuis, reticulis laxis; 
fructibus globosis, circiter 2.5 em diametro, 2-locellatis, in sic- 
citate brunneis, pericarpio 5 mm crasso, fragile. 
A glabrous tree (flowers not seen) about 10 m high, the 
branchlets slender, terete. Leaves chartaceous, entire, pale 
olivaceous, shining, of about the same color on both surfaces, 
oblong-ovate to elliptic-ovate, 10 to 17 em long, 4 to 7.5 em wide, 
the base acute to rounded, sometimes slightly inequilateral, the 
apex slenderly acuminate; lateral nerves about 5 on each side
