cent. Branches terete, the ultimate ones about 5 mm in dia- 

 meter, pale-brownish, pubescent, the branchlets very densely 

 and uniformly grayish-pubescent with short hairs, a similar 

 indumentum on the petioles, petiolules, and inflorescences. 

 Leaves alternate, about 25 cm long, the leaflets opposite, 3 or 

 4 pairs, pale when dry, oblong-elliptic to subelliptic, subcoria- 

 ceous, mostly 8 to 10 cm long and 4 to 5.5 cm wide, base some- 

 what inequilateral, rounded, apex obtuse to obscurely acuminate, 

 the upper surface glabrous except for the pubescent midrib, 

 the midrib and lateral nerves on the lower surface sparingly 

 pilose with spreading hairs ; lateral nerves somewhat impressed 

 on the upper surface, very prominent on the lower surface, 

 about 14 on each side of the midrib, slightly curved, obscurely 

 anastomosing, the reticulations subobsolete. Inflorescences axil- 

 lary, solitary, pubescent, 5 to 7 cm long, simple, racemose or 

 the nodes somewhat projecting and forming a very depauperate, 

 raceme-like panicle. Flowers about 7 mm long, 4-merous, some- 

 what crowded at the nodes, their pedicels about 1 mm long. 

 Calyx-lobes ovate, acute to obtuse, about 1.5 mm long, free nearly 

 to the base, slightly pubescent. Petals 4, oblong, obtuse, free, 

 7 mm long, 3 mm wide, externally very obscurely pubescent. 

 Staminal-tube cylindric, 6 mm long, glabrous, free, obscurely 

 crenate; anthers 8, 1 mm long, included. Disk cup-shaped, 2 

 mm long and wide, margins slightly undulate, glabrous outside, 

 somewhat pubescent inside. Ovary pubescent; style pubescent 

 in the lower one-half, glabrous above, including the ovary about

A characteristic species belonging in the group with Dysoxylum vrie- 

 seanum C. DC. It is most closely allied to Dysoxylum wenzelii Merr., of 

 Leyte, but is readily distinguishable by its more numerously nerved leaves 

 and different indumentum.
