POLYALTHIA PALAWANENSIS sp. nov. § Monoon. 
Arbor circiter 20 m alta, subglabra; foliis oblongis, chartaceis, 
usque ad 15 cm longis, in siccitate pallidis, nitidis, basi rotun- 
datis ad subacutis, apice prominente acuminatis, nervis utrinque 
circiter 9, tenuibus; floribus viridis, caulinis, fasciculatis, e 
tuberculis magnis, pedicellatis, sepalis leviter pubescentibus, pe- 
talis glabris, crasse coriaceis, oblongo-ovatis, obtusis, usque ad 
3.5 cm longis; carpellis numerosis, hirsutis, 1-ovulatis. 
A tree about 20 m high, glabrous except the younger parts 
and portions of the inflorescence. Branches slender, terete, 
wrinkled when dry, with small, scattered lenticels, brownish, 
the branchlets somewhat pubescent. Leaves oblong, charta- 
ceous, pale and shining when dry, 11 to 15 cm long, 4 to 5 cm 
wide, base rounded to subacute, apex rather prominently acu- 
minate; lateral nerves about 9 on each side of the midrib, 
slender, somewhat spreading, distant, anastomosing far from 
the margin, the reticulations slender, rather distinct; petioles 
about 4 mm long, glabrous. Flowers green or somewhat yellow- 
ish when mature, borne on large tubercles on the trunk, the 
tubercles 2 to 3 cm in diameter, very irregular, each bearing 
2 to 4 flowers; pedicels pubescent, stout, about 1 cm long. Sepals 
broadly ovate, coriaceous, obtuse, about 3 mm long and 4 mm 
wide, spreading or reflexed, sparingly pubescent externally, 
glabrous within. Petals thickly coriaceous, glabrous, ovate to 
oblong-ovate, obtuse, the outer ones up to 3.5 cm long and 1.7 
em wide, the inner somewhat smaller. Stamens indefinite, 
crowded, about 1.6 mm long, truncate, anther-cells entirely hid- 
den by the connectives. Carpels numerous, crowded, including 
the styles 1.7 mm long, the ovaries hirsute, oblong, the styles 
pubescent, as long as the ovaries. Ovule solitary, basal. 
PALAWAN, Lake Manguao, Merrill 9469, April 27, 1913, on dry forested 
ridges, altitude about 80 meters. 
A species in the group with Polyalthia macropoda King and allied forms, 
but quite different from this species and the others placed here. It has no 
close allies among the Philippine forms bearing the flowers on the trunk 
or on the larger branches. 
POLYALTHIA GIGANTIFOLIA sp. nov. § Monoon. 
Arbor circiter 20 m alta, inflorescentiis exceptis glabra; foliis 
oblongis, coriaceis, circiter 60 cm longis, nitidis, acuminatis, 
basi cordatis, nervis utrinque circiter 30, valde prominentibus; 
floribus 7 cm diametro, pedicellatis, plus minusve pubescentibus, 
in truncis fasciculatis. 
A tree about 20 m high, glabrous except the inflorescence.
