Leaves: blades coriaceous, narrowly oblong, narrowly elliptic or narrowly obovate, 8-15(-18) cm long, (1.5-)2-4 cm wide; apex acuminate, caudate or sometimes acute; base cuneate; margin recurved, entire or often distally with glandular teeth; both surfaces glabrous or sparsely cobwebby hairy, especially on midrib; lower surface densely papillose; midrib impressed on upper surface, very prominent on lower surface; nerves 8-13 pairs, prominent on both surfaces, rarely impressed on upper surface; petioles glabrescent to rusty tomentose, lengthwise deeply grooved when dry, 8-20 mm long. Inflorescence a contracted spike, from axils of leaves and/or on twigs, up to 1 cm long, the axis rusty tomentose; bracts orbicular, widely ovate or widely obovate, 2-3 mm long, apex rounded; bracteoles 2, ovate to oblong, 1.5-2 mm long, apex obtuse to rounded; both persistent, adaxially glabrous, abaxially rusty tomentose. Flowers: calyx tube glabrous, 0.5-0.8 mm high; calyx limb 1.5-2 mm long; calyx lobes, elliptic to oblong, 1-1.5 mm long, apex rounded to obtuse, outside tomentose; corolla white, 4-5.5 mm long, deeply 5-lobed, lobes elliptic; corolla tube about 1 mm long; stamens indistinctly pentadelphous, 35-55; disk annular, short cylindric or pulvinate, glabrous; style glabrous, 4-5.5 mm long; ovary 3-locular with 4 ovules in each locule. Fruits bluish black, (obliquely) ovoid, 12-19 mm by 6-8 mm; calyx lobes caducous or partly persistent; stones (obliquely) ovoid, shallowly grooved lengthwise or rather smooth, 10-17 mm by 5-7 mm; mesocarp thin; endocarp woody; seeds 1, straight with straight embryo.
