Characteristics

Deciduous tree up to 14 m. tall with a deeply corrugated bark and a flatly rounded crown, the branches at least sometimes pendulous.. Twigs brittle, hairy at first, later glabrescent.. Leaves petiolate; blade elliptic-lanceolate, narrowly elliptic or elliptic, up to 14 times as long as wide, commonly 4.5–12 cm. long, l–2(–3.5) cm. wide, very acute to slightly retuse on the shorter broader leaves, mucronate, basally narrowed, moderately densely hairy, especially beneath and when immature, or glabrous to nearly so, but usually hairy at least on the midrib beneath; petiole 8–15 mm. long, wrinkled and usually hairy.. Inflorescence an axillary or terminal rather dense raceme, 2.5–7 cm. long, often developing at about the time of leaf-fall; pedicels widely spreading, 3–7 mm. long, densely pubescent.. Sepals ovate-oblong, sometimes narrowly so, ± 3–4.5 mm. long, later reflexed, green, pubescent, sometimes particularly on the margin; receptacle with a very pronounced cushion-like apex.. Stamens 14(–18); filaments (4–)5–8 mm. long, white; anthers ± 1.75 mm. long, yellow.. Ovary ovoid, green; stigma sessile or borne on a thick style up to 0.5 mm. long.. Fruits spheroid, 15–20 mm. in diameter, smoothly verruculose, glabrous.

A medium sized tree. It can grow to 15 m high. It loses its leaves during the year. The bark is dark grey, rough and flaky. The leaves are alternate, long and narrow.

The stamens are yellowish-green. The fruit is round and 2 cm across. They are smooth and yellow when ripe. They have 1-3 seeds. The seeds are brown and 1 cm across.
Leaf-lamina 4–15 x 0.8–4.5 cm., linear, linear-lanceolate, narrowly elliptic, oblanceolate or oblong, apiculate, long-acuminate, acute or more rarely blunt at the apex, cuneate at the base, pubescent or scaberulous above, often glabrescent later, more persistently pubescent below; midrib prominent below; petiole up to 1.5 cm. long, pubescent.
Inflorescence of axillary racemes, 2–4 cm. long, often flowering at about the time of leaf-fall or sometimes a little later; peduncles very short, 2–5 mm. long, densely pubescent; pedicels 2–5 mm. long, densely pubescent; bracteoles c. 1 mm. long, subulate, densely pubescent, entire or with two side teeth.
Sepals greenish-yellow, c. 3 x 1.7 mm., reflexed at maturity, oblong-lanceolate to narrowly ovate, acute at the apex, pubescent within, densely velvety-pubescent outside, densely ciliate at the margins; receptacle 4-sided, papillose-fimbriate.
Ovary ovoid, glabrous, with about 10 ovules on 2 placentas; style c. 0.6 mm. long; stigma small, not much wider than the style.
Deciduous tree up to 15 m. tall, but often much less; bark dark grey, rough and flaking; young branches densely pubescent.
Seeds brown, c. 1 cm. in diam., globose or somewhat compressed, rugose, embedded in a fleshy pulp.
Fruit c. 1.7 cm. in diam., globose, almost smooth, yellowish, with a minute apiculus, 1–3-seeded.
