Description from Flora of China
Trees evergreen, ca. 9 m tall. Branchlets pubescent or glabrescent; young branchlets terete, longitudinally angular; third year’s branchlets cinereous, longitudinally plicate and fissured, with semicircular leaf scars and raised inflorescence scars; terminal buds conical, pubescent or glabrous. Leaves on first to second year’s branchlets; petiole brown or black when dry, 9-15 mm, slender, sparsely puberulent; leaf blade abaxially pale green, adaxially green, obovate-lanceolate, narrowly elliptic, lanceolate, or oblanceolate, (6-)8-13.5 × (2-)3-4.5 cm, leathery, abaxially glabrous, sparsely minutely glandular punctate, adaxially glabrous except on midvein slightly pubescent, midvein impressed adaxially, lateral veins 7 or 8 pairs, obscure adaxially, reticulate veins obscure on both surfaces, base obtuse, margin undulate-crenulate, apex shortly acuminate. Inflorescences: cymes, pubescent or glabrous, fasciculate, axillary on second year’s branchlets, base of fascicles with persistent scales of flower buds, reniform, pubescent or glabrous; flowers yellow-white, 4-merous. Male inflorescences: cymes of order 2, 3-flowered; bracts broadly ovate, pubescent, with basal, stipulelike, pubescent appendages; peduncles 1-2 mm, densely pubescent; pedicels 3-4 mm, pubescent; bracteoles 2, basal or submedian; calyx patelliform, 2-2.5 mm in diam., sparsely pubescent, 4-lobed, lobes orbicular, ciliate; petals 4, oblong-obovate, ca. 3 × 2 mm, glabrous, margin sparsely ciliate, basally slightly connate; stamens ca. as long as petals, anthers ovoid; rudimentary ovary subglobose or ovoid, apex rounded or obtuse. Female inflorescences: 1-flowered cymes; pedicels ca. 3 mm, bracteoles 2, basal; calyx and corolla as in male flowers; staminodes ca. 1/3 as long as petals, sterile anthers sagittate; ovary ovoid, ca. 2 mm in diam., apex truncate, stigma discoid. Fruit red, cinereous when dry, globose, ca. 1 cm in diam.; fruiting pedicel 2-6 mm; persistent calyx explanate, ca. 2.5 mm in diam., pubescent and ciliate; persistent stigma navel-like, ca. 3 mm in diam.; pyrenes 4, broadly ellipsoidal, 6-7 mm, 4-4.5 mm in diam., both ends acuminate, abaxially palmately striate and sulcate, laterally rugose and pitted, endocarp woody. Fl. Apr-May or Aug-Oct, fr. May-Dec.
