Description - Shrub or tree 3.0-10.0, sometimes up to 25.0 m tall; trunk up to 65.0 cm diam; bark gray, rather smooth. Branchlets glabrous or appressed-puberulous, rarely patently pubescent or even tomentulose at tips. Leaves oblong to narrowly or broadly elliptic, apex shortly more or less bluntly acuminate, base cuneate to almost rounded, the very base with 2 dark glands above, chartaceous to subcoriaceous, rarely coriaceous, glabrous or not rarely short-pubescent on midrib and nerves beneath, sometimes softly tomentulose all over the undersurface particularly when young, generally coarsely and irregularly crenate-serrate, mainly so in the upper half of the lamina, rarely remotely and obscurely so, or even subentire, 7.0-18.0(-22.0) cm long, 4.0-6.0(-11.0) cm broad, 3-nerved from base (an outer pair of basal nerves very faint), with 3-4(-5) lateral nerves from the upper half of the midrib, all nerves prominent mainly beneath, veins more or less transverse, forming a dense network with the veinlets which is finely raised on both faces; petiole pubescent, glabrescent or glabrous, (0.7-)1.0-3.0(-4.0) cm long; stipules subulate, 1.5-2.0 mm long, caducous. Inflorescences (sub)terminal, few- to many-flowered, up to 18.0 cm long and wide, the partial inflorescences consisting of cymes or panicles which are laxly and more or less umbellately arranged, on stoutish peduncle up to 5.0 cm long, all over puberulent, tomentellous or short-tomentose; pedicels slender, up to 1.0 cm long. Flowers cream, greenish or whitish, sometimes with reddish hue. Sepals 4 (very rarely 3), narrowly or broadly ovate, subacute, puberulous to tomentellous on both faces, 2.5-3.0 (rarely -4.5) mm long, 1.5-2.5 (rarely -3.0) mm broad. Petals rather narrowly obovate, subacute, of the same number as and similar to the sepals. Receptacle laxly hairy. Disk consisting of 8 small flattish glands. Stamens 30-40; filaments sparsely hairy below. Ovary ellipsoid, attenuate to substipitate at base, glabrous or laxly to densely short-pubescent; style very slender, 1.5-2.0 mm long. Berry subglobose, glossy, dark red to blackish, glabrescent, 6.0-7.0(-13.0 ?) mm diam; seeds 1 or 2, ovoid-compressed, 3.0-4.0 mm long, ca 2.0 mm broad.
