Description

Tree to 30 m tall, usually much smaller; young branches fulvous-tomentose, becoming glabrous with age. Stipules triangular, 2-4 mm long, pubescent, subpersistent. Petiole 6-16 mm long, tomentose, canaliculate; blade thickly coriaceous, elliptic to obovate-oblong or oblong, 3-25 x 3-9 cm, obtuse to shortly acuminate at apex, acumen 0-10 mm long, rounded to cuneate and often slightly unequal at base, usually plane rarely slightly bullate above, sparsely to densely hirsutulous beneath; midrib impressed above, prominent and pubescent when young beneath, 8-22 pairs of secondary veins, arcuate, anastomosing near margin. Inflorescence a dense glomerule on upper portion of petiole. Flowers hermaphrodite, sessile or pedicels 0.25-2 mm long; bracteoles 0.5-1 mm long, persistent, tomentose; calyx 3.5-5.5 mm long, tomentose on exterior, lobes unequal; corolla yellowish, exceeding calyx lobes, with 2 larger bicucullate lobes and 3 smaller simple lobes, united at base into a very short tube, tube glabrous on exterior, filled by a lanate mass of hair within; fertile stamens 3, alternating with corolla lobes, and inserted at mouth of short corolla tube, 2 staminodes present; ovary 3-locular, pilose on exterior, style with 3-fid apex, pubescent throughout. Fruit oblong-ellipsoid, to 3 cm long, 1-2-locular, epicarp shortly appressed velutinous pubescent, mesocarp 1-4 mm thick, endocarp thin, hard, bony, glabrous within.
