Characteristics

Tree 3–8 m. Bark dark brown, flaking longitudinally; inner bark dark brown; wood cream. Twigs cicatrose, the leafy ones 5–7 mm diam. Young twigs and buds ± fulvous strigose (in sicco). Apical buds with fist-shaped young leaves. Leaves 25–40 cm, imparipinnate, 2–5-jugate; petiole 4–7.5 cm, 2–3 mm diam., flattened to shallowly channelled adaxially (in sicco), ± densely strigose, base weakly swollen; rachis c. 2 mm diam., flattened adaxially (in sicco), glabrescent to strigose. Leaflets opposite to subopposite, pale abaxially, glabrous adaxially, finely sericeous to fawn strigose, particularly on veins; abaxially, the terminal the largest, to 20 by 7 cm, oblong to obovate, base acute to subcuneate, apex acute to subacuminate, the laterals smaller the more proximal, when ovate, bases rounded to subacute, costae c. 9–12 on each side, arcuate, prominent abaxially, petiolule 0–3(–10) mm (–15 mm on apical leaflet). Spikes c. 3–6(–12) mm, axillary or on twigs, ± strigose; bracts c. 1 mm long, ovate, densely hairy. Flowers ± sessile. Calyx c 2 mm long, cupulate, sometimes shortly pseudopedicellate, margin truncate to shallowly irregularly lobed, densely adpressed pubescent without. Petals 4, c. 7 mm long, narrowly spatulate, imbricate at apices, glabrous, white. Staminal tube glabrous, 8-ribbed with 8 emarginate to shallowly bifid lobes, white; anthers 8, c. 1 mm long, oblong, subsessile, on ribs alternating with lobes, included. Disk c. 2 mm long, margin crenate, glabrous except for a few long setae sometimes at margin. Ovary 3-or 4-locular, adpressed pubescent; style pubescent in proximal half, terete; stylehead discoid to subcapitate. Capsules solitary or in fascicles of up to 4, 4 cm long, c. 2 cm diam., obovoid to ellipsoid, stipitate, apiculate, subglabrous, conspicuously lenticellate, orange-red, dehiscing with 3 or 4 valves; pericarp with weak watery latex. Seeds 3 or 4, c. 2 cm long, plano-convex, red, (?arillate).
