Leaves spaced or loosely clustered, spirally arranged, 7.7-18 × 3.4-7.5 cm, oblanceolate, apex usually rounded, or obtuse, base narrowly attenuate, chartaceous, glabrous; venation eucamptodromous, midrib raised on the upper surface, marginal vein present, seconary veins 7-10 pairs, parallel or slightly convergent, slightly arcuate or straight; intersecondaries absent; tertiaries oblique. Petiole 1-2 cm long, not channelled, glabrous. Fascicles 3-15-flowered, in the axils of fallen leaves. Pedicel 3-5 mm long, with sparse minute appressed hairs. Flowers unisexual (plant dioecious). Sepals five, 3-3.5 mm long, broadly ovate, apex obtuse or rounded, subglabrous outside, closely sericeous inside. Corolla cyathiform or shortly tubular, 3.5-5 mm long, tube equalling or shorter than the lobes (male), longer than the lobes in female, lobes five, ovate, apex obtuse or rounded, auriculate, glabrous. Stamens five, fixed about halfway up the corolla tube (female with vestigial filaments fixed in the upper half of the tube); filaments 1-1.5 mm long (conspicuous traces visible to base of tube), geniculate at apex, glabrous; anthers 1.25-1.5 mm long, lanceolate, apiculate, glabrous, absent in female. Staminodes five, 1.75-2.5 mm long (male), ca. 0.5 mm long (female), narrowly lanceolate to triangular, glabrous.
