918 LEAFLETS OF PHILIPPINE BOTANY [Vor. III, Arr. 51 
Collected it in gravelly soil of wooded banks along the 
Sinuban creek at 750 feet. Commonly observed but the spec- 
imens were gathered at least a month too early for mature 
fruits. The Sibuyan Visayan name is ''Leocum."' 
General aspects are that of a Gelonium, but the generic 
description is quite different for the staminate flowers in 
our material.

branched from the middle, rebranched and ultimately widely 
spreading; wood moderately -soft or rather hard, whitish, 
odorless and tasteless; bark smooth, brown. Leaves coriaceous, 
descehdiug, flat, lucid bright green above, duller and a trifle 
paler green beneath, glabrous except the nerves, beneath, 
alternate, only a few at the ends of the smooth twigs, en- 
tire, usually acute at apex, rounded or obtuse at base, ellip- 
tic, the larger blades 17.5 em. long, 7.5 cm. wide across 
the middle, in the. dry state retaining its color; pet- 
iole 1 em. long, green, very finely puberulent, midvein
