Cremastosperma cauliflorum R. E. Fr.

Tree 2–20 m tall, 4–25 cm diam.; young twigs and petioles glabrous to rather densely covered with appressed or erect golden hairs to 0.5 mm long. Leaves: petioles 4–12(–16) by 2–4(–6) mm; lamina elliptic to obovate or narrowly so, (14–)20–61 by 5–14(–22) cm (index 2.3–3.7), chartaceous, olive/brown green above, darker below, glabrous above except for base of primary vein sparsely covered with appressed or erect hairs to 0.3 mm long, base, primary and secondary veins sparsely to rather densely covered with appressed or erect golden hairs to 0.5 mm long below, base acute to obtuse, apex acuminate (acumen 5–45 mm long), primary vein verrucose (particularly at the base), deeply grooved for most of length, 1.5–3.5(–5) mm wide at widest point, secondary veins (6–)10–17, occasionally 1–2 intersecondary veins, distance between from 4 mm at the base to up to 40 mm closer to the apex, angles with primary vein from 45–70° at the base to 45–60° closer to the apex, not branching, forming mostly distinct loops, smallest distance between loops and margin 1–5 mm, tertiary veins percurrent. Inflorescence of 1–5 flowers, branching, solitary or clustered in groups of up to 7, on thick leafless twigs or on main trunk (then often on brachyblasts); peduncles 3–12(–15) by 1–1.5(–3) mm (in flower), 3–15 by 1–3 mm (in fruit); pedicels 10–45 by 1–3 mm at the base (in flower), 15–45 by 1–3 mm (in fruit), peduncles and pedicels rather densely to densely covered with mainly erect golden hairs ca. 0.3 mm long, often with hairs more densely covering the articulation point between shoot and pedicel; single lower bract (from the axil of which short shoots develop bearing new flowers), deltate, 1.5–2 mm long, acute, soon falling off, densely covered with mostly appressed golden hairs to 0.3 mm long; upper bract attached around midway along pedicel, broadly to very broadly ovate or deltate, 2–4 mm long, obtuse or acute, outer side densely covered with appressed or erect golden hairs to 0.3 mm long; closed flower buds depressed ovoid, opening in development; flowers (pale) green, creamy white, greenish-yellow or yellow in vivo, brownish-yellow or brown with orange, dark brown or black base in sicco, outer side of sepals and petals densely covered with erect or appressed golden hairs to 0.4 mm long, inner side of sepals and petals sparsely to rather densely covered with erect hairs to 0.4 mm long or glabrous, base glabrous; sepals free, broadly to very broadly ovate-deltate, mostly recurved, 3–5 by 4–6 mm, obtuse, soon falling off; outer petals elliptic to broadly elliptic, 10–25(–32) by 9–17 mm, inner petals elliptic, 11–21(–32) by 6–11 mm; androecium 7–10 mm diam., stamens 1.5–2 mm long, connective appendage 0.7–1 mm wide; gynoecium 2–3 mm diam., carpels ca. 40, 2–2.3 mm long, sparsely to rather densely covered with mostly appressed golden hairs to 0.2 mm long. Monocarps 9–41, globose to transversely broadly ellipsoid, slightly asymmetrical, 8–13 by 10–14 mm, green maturing to orange, red, brown and black in vivo, blackish-brown or brown in sicco, sometimes with an apicule at or near the apex; stipes 7–23(–32) by 1–2 mm; fruiting receptacle depressed ovoid, 4–11 mm diam; monocarps, stipes and receptacle rather densely covered with erect golden hairs to 0.2 mm long. Seeds broadly ellipsoid to globose, orange, pitted, 9–10 by 9–10 mm, raphe sunken, regular.
