Terminal buds large, ovoid, ca. 6 × 5 mm; bud scales densely imbricate, broadly ovate, brown sericeous-pubescent, apex obtuse or apiculate. Leaves alternate, always inserted on upper part of young branchlets; petiole tea-brown, 2-3 cm, plano-convex, glabrous; leaf blade yellow-brown abaxially and yellow-green adaxially when dry, oblong-elliptic or ovate-elliptic, 7.5-9.5(-10) × 4-5(-6) cm, papery to subleathery, glabrous on both surfaces, pinninerved, lateral veins 4 or 5 pairs, arcuate-ascendant, anastomosing within leaf margin, lateral veins and midrib conspicuous on both surfaces, axils of lateral veins dome-shaped and puberulent abaxially, bullate adaxially, transverse veins and veinlets reticulate, foveolate on both surfaces, base broadly cuneate to subrounded, ± slightly asymmetric on sides, margin cartilaginous and involute, apex shortly acuminate. Panicles tea-brown when dry, terminal and axillary, short, 3-5 cm, subglabrous or slightly puberulent at base, branched almost from base; branches patent, ca. 2 cm, terminal one bearing a cyme. Pedicels ca. 2 mm, slightly dilated at base, glabrous. Flowers white or purple-red, scented, ca. 2.5 mm. Perianth glabrous outside, densely villous inside; perianth tube campanulate, ca. 1.2 mm; perianth lobes 6, narrowly ovate, ca. 1.3 mm, obtuse at apex. Fertile stamens 9, ca. 1 mm; filaments villous at base, a little longer than anthers, complanate, those of 3rd whorl each with 2 shortly stalked suborbicular-reniform glands near base, others glandless; anthers broadly oblong, 4-celled; cells lateral-introrse (of 1st and 2nd whorl) or lateral-extrorse (of 3rd whorl). Staminodes 3, including stalk ca. 0.8 mm, triangular-subulate; stalk ca. 0.4 mm. Ovary ovoid, ca. 0.6 mm, abruptly attenuate into a ca. 0.6 mm long style; stigma capitate. Fruit shiny, greenish when fresh, ellipsoid, 1.5-2.2 × 1.5-2 cm, maculate, glabrous; perianth cup in fruit urceolate, ca. 9 mm, column base ca. 2 mm long and broad, abruptly dilated into a trumpet toward apex, trumpet ca. 9-10 mm wide, margin entire or undulate.

An evergreen tree. It grows 20 m tall. The bark is reddish brown and cracked. The leaves are alternate and narrowly oval. They are 8-10 cm long by 4-5 cm wide. They are wedge shaped at the base and taper to the tip. The leaf stalk is smooth and 2-3 cm long. The flowers are small and have both sexes. They are white or pale and hairy. They are in groups in the axils of leaves or at the ends of branches. These are 3-5 cm long. The fruit are oval and 15-22 mm long by 15-20 mm wide.
Can be grown by cuttings or seedlings. Seeds needs soaking.
