Leaves: petioles 8–12(-18) by 3–4 mm; lamina narrowly elliptic to elliptic, 17–42 by 7–13 cm (index 1.8–3.9), chartaceous, olive green or brown on both sides, venation darker below, glabrous above, rather densely covered with appressed whitish-golden hairs to 0.2 mm long on veins below, base acute, apex acute to acuminate (acumen 5–15 mm long), primary vein grooved over entire leaf length, verrucose at the base, 3–4 mm wide at widest point, secondary veins (8-)10–15, occasionally 1 or 2 intersecondary veins, distance between from 4–9 mm at the base, 20–50(-60) mm in the centre to 10–30 mm closer to the apex, angles with primary vein from 40–50° at the base to 70–80° closer to the apex, occasionally branching, forming more or less distinct loops in the apical half, tertiary veins percurrent. Inflorescence of 1–8 flowers, branching, solitary or clustered in groups of 2, on leafless twigs and branches; peduncles 7–22 by 1–1.5 mm (in flower), 10–22 by 2.5–3 mm (in fruit); pedicels 25–38 by ca. 1 mm at the base, 1.5–2 mm at the apex (in flower), 25–38 by 2–3 mm at the base, 2–4 mm at the apex (in fruit), peduncles and pedicels rather densely to densely covered with appressed whitish to golden hairs to 0.2 mm long; single lower bract, soon falling off; upper bract attached around halfway along the pedicel, broadly to depressed elliptic or broadly to depressed ovate, 1–2 by 1.5–1.8 mm, obtuse, outer side densely covered with appressed whitish-golden hairs to 0.2 mm long; closed flower buds depressed ovoid, opening early in development; flowers green, maturing to greenish-yellow or cream in vivo, brown in sicco; sepals fused for first 0.5 mm, deltate, appressed (basal 1 mm of sepals and petals reflexed), 2.5–3 by ca. 3 mm, acute or obtuse, soon falling off, inner side glabrous, outer side rather densely to densely covered with appressed whitish-golden hairs to 0.2 mm long; outer petals elliptic, 8–15 by 5–9 mm, inner petals elliptic, 12–14 by 5–7 mm, inner side of inner and outer petals glabrous, most of outer side of outer petals rather densely to densely covered with appressed whitish-golden hairs to 0.2 mm long (towards the margins and apex glabrous), outer side of inner petals largely glabrous but with a narrow, dense, sometimes branching band of appressed, whitish-golden, to 0.2 mm long hairs extending from the base to halfway towards the apex; receptacle depressed ovoid; androecium ca. 6 mm diam., stamens 1–1.5 mm long, connective appendage 0.5–0.8 mm wide; gynoecium ca. 2 mm diam., carpels up to ca. 40, ca. 1.5 mm long, glabrous or sparsely covered with appressed, whitish-golden, to 0.2 mm long hairs. Monocarps 16–37, ellipsoid, asymmetrical, 12–20 by 10–13 mm, green maturing to dark purple or black in vivo, black in sicco; stipes 20–30 by 2–3 mm; fruiting receptacle depressed ovoid, 7–12 mm diam., monocarps, stipes and receptacle glabrous. Seeds ellipsoid, brown, lightly furrowed (not pitted), ca. 13 by 9 mm, raphe neither sunken nor raised, encircling seed longitudinally.
