GUIOA BICOLOR sp. nov. 
Arbor parva, partibus junioribus leviter pubescens; foliis 25 
ad 30 cm longis, foliolis plerumque 9, crasse coriaceis, oblongo- 
ovatis ad oblongo-ellipticis, 9 ad 12 cm longis, acute acuminatis,

A small tree, the younger parts sparingly pubescent, the older 
parts glabrous. Branchlets dark reddish-brown or nearly black 
when dry. Leaves 25 to 30 cm long, the leafiets usually 9, 
thickly coriaceous, oblong-ovate to oblong-elliptic, 9 to 12 cm 
long, 3.5 to 5.5 cm wide, the base somewhat inequilateral, the 
apex rather sharply acuminate, the upper surface brownish when 
dry, glabrous, shining, the lower surface glaucous and sparingly 
pubescent with short, widely scattered hairs; lateral nerves about 
9 on each side of the midrib, distinct, the reticulations not prom- 
inent; petiolules up to 1 cm in length, their bases much thick- 
ened. Panicles axillary, up to 15 cm long, branched from the 
base, very slightly pubescent. Flowers white, numerous; sepals 
unequal, 2 to 2.5 mm long. Petals narrowly obovate, 1.5 mm 
long, their margins slightly ciliate, the villous scales about as

This species is rather radically different from the previously 
described Philippine representatives of the genus in its thickly 
coriaceous leaflets which are glaucous on the lower surface.
