Leaves: petioles 10–15 mm long, 2.5–7 mm diam.; lamina narrowly elliptic to elliptic, 35–60 by 10–25 cm (leaf index 2.3–3), chartacous to subcoriacous, olive/dark brown above, lighter below, glabrous above, sparsely covered with white-golden appressed hairs ca. 0.4 mm long on veins below (densely so developing leaves), base acute, apex acuminate (acumen 10–15 mm long), primary vein deeply grooved in basal half, 2–6 mm wide at widest point; secondary veins 10–16, intersecondary veins rare, distance between from 10 mm at the base to 80 mm closer to the apex, angles with primary vein 45° at the base to 60–70° closer to the apex, not branching, forming distinct loops in the apical half to third of the leaf, smallest distance between loops and margin 3–4 mm; tertiary veins mainly percurrent. Inflorescences of single, pendulous flowers, produced from leafless branches; peduncles 5–8 by ca. 1 mm (in flower), ca. 4 by 2 mm (in fruit); pedicels 90 (less mature) – 210 by 1 mm at the base, 1.5 at the apex (in flower), ca. 240 by 2 mm at the base, 3 mm at the apex (in fruit); peduncles and pedicels sparsely to rather densely covered with white-golden appressed hairs ca. 0.4 mm long; single lower bract, broadly elliptic, 1–2 by ca. 1 mm, acute, soon falling off, densely covered with white-golden appressed hairs ca. 0.4 mm long; upper bract attached on lower half of pedicel, elliptic, 1.5–3 by ca. 1 mm, acute, densely covered with white-golden appressed hairs ca. 0.4 mm long; closed flower buds not seen; flowers green (immature) in vivo, medium brown in sicco; sepals free, triangular to broadly trullate, appressed, 3–4.5 mm long, acute, soon falling off, rather densely to densely covered with white-golden appressed hairs ca. 0.4 mm long; outer petals elliptic, ca. 22 by 12 mm, inner petals narrowly elliptic, ca. 22 by 6 mm, sparsely to rather densely covered with white-golden appressed hairs ca. 0.4 mm long; stamens ca. 1.2 mm long, connective appendage ca. 1 mm wide. Monocarps ca. 20, black in sicco, ellipsoid, slightly asymmetrical, ca. 20 by 12 mm, without an apicule; stipes ca. 25 by 2 mm; fruiting receptacle ovoid, 8 mm diam.; monocarps and stipes glabrous, receptacle sparsely covered with white-golden appressed hairs ca. 0.4 mm long. Seeds ellipsoid, 18–20 by 8–9 mm, orange/brown, with many shallow pits, raphe slightly raised, encircling seed longitudinally.
