Pseuduvaria diepenhorstii Miq.). 
PSEUDUVARIA P H I Li PPI N ENSIS sp. nov. 
Arbor dioeca, 10 ad 15 m alta, plus minusve molliter pubes- 
centibus; foliis oblongis ad oblongo-lanceolatis, chartaceis ad 
subcoriaceis, usque ad 16 cm longis, acuminatis, basi acutis, 
supra, costa exceptis, glabris, nitidis, subtus pallidis, molliter 
pubescentibus, nervis utrinque circiter 10, prominentibus ; flor- 
ibus 8 numerosis, axillaribus, fasciculatis, longe pedicellatis, 
pubescentibus, petalis exterioribus ovatis, quam sepalis paullo 
majoribus, interioribus valde diversis, longe unguiculatis, circi- 
ter 6 mm longis; staminibus circiter 50, uvarioideis. 
A tree 10 to 15 m high, dioecious, more or less softly pubescent. 
Branches terete, dark-colored when dry, more or less wrinkled, 
glabrous, the young branchlets rather densely and softly pubes- 
cent with pale or subferruginous hairs. Leaves chartaceous to 
subcoriaceous, rather pale when dry, shining, oblong to oblong- 
lanceolate, 9 to 16 cm long, 3 to 4.5 cm wide, base acute, the 
apex rather prominently acuminate, the upper surface brownish- 
olivaceous or rather pale, glabrous except the more or less pubes- 
cent midrib, the lower surface much paler than the upper, rather 
softly pubescent with grayish hairs; lateral nerves about 10 
on each side of the midrib, prominent, curved-ascending, anas- 
tomosing, the reticulations lax, distinct; petioles about 3 mm 
long, pubescent, ultimately subglabrous. Male flowers numer- 
ous, axillary and in the axils of fallen leaves, yellow, 2 to 10 
in a fascicle, their pedicels about 1.5 cm long, densely pubescent, 
the buds depressed-globose. Sepals 3, broadly ovate, obtuse, 
densely pubescent, about 1.5 mm long. Outer 3 petals quite 
similar to the sepals but 2 mm long; inner 3 petals entirely 
different from the outer, clawed, arched, about 6 mm long, 
pubescent, coriaceous, the claw slender below, widened above, 
about 4 mm long, the limb 3.5 to 4 mm wide, cohering by the 
lateral margins leaving an opening in the center above the 
stamens. Stamens about 50, uvarioid, densely crowded on the 
pubescent torus, about 0.7 mm long, truncate, the anther-cells 
concealed by the connectives. Pistillate flowers not seen.

Probably referable here is Merrill 9218 from Palawan, the specimen in 
fruit. 
The alliance of this species is with the Sumatran Pseuduvaria diepen- 
horstii T. & B., which it greatly resembles. It is distinguished, however, 
by its indumentum and its fewer nerved leaves.
