A small tree, the younger branchlets and inflorescences 

 densely ferruginous-pubescent, the petioles and midribs on the 

 lower surface of the leaves also pubescent. Branches terete, 

 reddish-brown, glabrous. Leaves subcoriaceous, brownish to 

 subolivaceous when dry, shining, of about the same color on 

 both surfaces or somewhat paler beneath, oblong-ovate to 

 oblong-elliptic, 11 to 20 cm. long, 4 to 9 cm. wide, the base 

 rather broadly acute, not rounded, apex prominently acu- 

 minate, the acumen often slender, the margins crenate-apicu- 

 late, the lower surface minutely and obscurely glandular, 

 glabrous except the midrib : lateral nerves about 13 on each 

 side of the midrib, very prominent, curved, ascending, anasto- 

 mosing, the reticulations slender, subparallel ; petioles 4 to 

 10 cm. long. Racemes axillary and in the axils of fallen 

 leaves, solitary, equaling or somewhat longer than the petioles, 

 rather densely pubescent, many flowered. Flowers yellowish, 

 5-merous, their pedicels 7 to 9 mm. long, the buds ovoid. 

 Sepals oblong, acuminate, about 5 mm. long, 1.5 to 2.3 mm. 

 wide, uniformly and densely pubescent on both surfaces. 

 Petals oblong, narrowed at both ends, about 6 mm. long, 2.5 

 mm. wide, both surfaces densely pubescent, the hairs on the 

 inner surface reflexed, the apex acute, entire or very obscurely 

 2- or 3-toothed. Stamens about 40 ; filaments about 1 mm. 

 long; anthers oblong-obovoid, rounded, scabrid, 1-to 1.2 mm. 

 Jong, the tip not bearded. Ovary densely pubescent, ovoid.
