Tree c. 7 m tall, c. 12 cm diam; young twigs densely covered with erect hairs, soon glabrous. Leaves: petiole 8–10 mm long, 2–3 mm diam; lamina elliptic to oblong-elliptic, 6–16 by 3–6 cm (leaf index 2–2.6), chartaceous, not verruculose, dull, brown above, brown below, sparsely covered with erect hairs above, sparsely to rather densely covered with erect, brown hairs below, base obtuse, apex acuminate (acumen 10–20 mm long), primary vein impressed above, secondary veins distinct, 8–12 on either side of primary vein, impressed above, small- est distance between loops and margin 1–2 mm, tertiary veins slightly raised above, reticulate to slightly percurrent. Flowers in 1–2-flowered inflorescences, on leafless branchlets or on the stem; pedicels 10–25 mm long, c. 1 mm diam, fruiting pedi- cels c. 2 mm diam, densely covered with erect, brown hairs, articulated at c. 0.1 from the base, bracts soon falling, not seen; flower buds not seen; sepals free, broadly ovate-triangular, 6–7 by 7–8 mm, appressed, outer side densely covered with appressed hairs; petals yellow in vivo, oblong-elliptic, 10–15 by 6 –10 mm, outer side densely covered with appressed, brown hairs; stamens not seen. Monocarps c. 25, green in vivo, black in sicco, ellipsoid to ovoid, 11–12 by 8–9 mm, glabrous, apex bluntly apiculate (apiculum 1–2 mm long), wall 0.1–0.2 mm thick, stipes 21–23 by 1–2 mm.
