Characteristics

A much-branched evergreen tree with a dense rounded crown, up to 15 m. tall; bole up to 2 m. girth; bark grey or blackish, tessellated or fissured.. Branchlets more robust than in U. nitida, but not usually as robust as in U. kirkiana; twigs glabrous, or else pubescent and soon glabrescent.. Leaves: petioles usually 1–2 cm. long, rarely up to 5.5 cm. long, fairly slender; leaf-blades oblanceolate or obovate-oblanceolate, (5–)10–15(–20) cm. long, (2–)4–7(–11) cm. wide, widest in the upper 1/3, rounded or rarely obtuse at apex, attenuate to a ± symmetrically cuneate or narrowly rounded-cuneate base, thinly coriaceous, midrib commonly distally zigzag, lateral nerves 7–13(–15) pairs, mostly camptodromous, a few distal brochidodromous, somewhat impressed above, prominent beneath, tertiary nerves subparallel, sparingly minutely lepidote or pubescent above and beneath at first, later glabrescent, grey-green or bright green and shiny above, paler and duller beneath, the midrib and nerves yellowish.. Stipules 0.. Inflorescences usually borne among or just below the leaves, rarely on the older wood, solitary.. Male peduncles 0.5–2.5 cm. long, often with 1–3 small empty bracts along them; main inflorescence-bracts 9–10, elliptic-oblong to elliptic-ovate, 3–7 mm. long, 2–5 mm. wide, rounded, strongly concave, the outer ones with a pronounced midrib, glabrous or sparingly pubescent without at the base, glabrous within, yellow, sticky; head of male flowers 5–6 mm. across.. Male flowers: calyx-lobes 4–5, squarish, 1 mm. long, truncate, pubescent at the apex; stamens 4, filaments 1 mm. long, flattened; anthers 0.5 mm. long, sulphur-yellow; pistillode cylindric-obconic, 1 mm. high, densely pubescent.. Female peduncles 0.5–1 cm. long; bracts ± as in male.. Female flower: calyx shallowly cupular, 5-lobed, the lobes rounded, 0.5 mm. long, pubescent at the apex; ovary subglobose, 3-locular, 5 mm. in diameter, verruculose, subglabrous; styles 3, 3.5–4 mm. long, flabelliform, bipartite, the lobes each further divided into 2–3 ligulate segments, greenish yellow, overlying the upper half of the ovary.. Fruits ellipsoid, 1.6–2 cm. long, 1.4–1.6 cm. in diameter, sparingly verruculose, faintly 9-ribbed, yellow to orange-red.. Pyrenes 3, 1–1.3 cm. long, 8–9 mm. wide, very shallowly carinate, slightly cuspidate at the apex.. Fig. 105, p. 569.

Leaf blades (3)5–21(25) × (1.5)2.5–11(15) cm, obovate to oblanceolate, rounded at the apex, attenuate to a cuneate or narrowly rounded-cuneate base, thinly coriaceous, glabrous above, sparingly hirsute-pubescent to subglabrous or glabrous beneath, deep green and glossy above, paler and duller or greyish-green beneath; midrib usually distally zigzag, lateral nerves in (5)7–14 pairs, rarely with interstitials, mostly camptodromous, the distal 3–4 pairs sometimes brochidodromous, somewhat impressed above, prominent beneath, tertiary nerves subparallel.
A small to medium sized tree. They are 6-10 m high. The bark is dark grey and rough. The leaves are scattered or clustered near the ends of branches. They are oval and 5-14.5 cm long by 2.3-7 cm wide. They are stiffly leathery. They are dark green above and paler underneath. The edges are rolled under. The flowers are greenish-yellow. The fruit are yellow and round. They are 1.5-2 cm across. The fruit stalks are 1.4-2 cm long.
An evergreen tree up to 25 m high, with divaricate branches, a dense rounded crown and a clear bole up to 6 m; bark smooth, striate, or finely quadrangularly fissured and peeling in small flakes, dark grey or blackish; stilt roots rarely produced; young twigs fairly slender to quite robust, ± glabrous.
Female flower: calyx 4 mm in diameter, shallowly cupular, 5-lobed, the lobes 0.5 mm long, rounded, pubescent at the apex; ovary 4–5 × 3–4 mm, ovoid-subglobose, 3(4)-locular, smooth, glabrous; styles 3(4), 4–6 mm long, flabelliform, laciniate, flattened, smooth, pubescent at the base, greenish-yellow.
Male peduncles 1–3 cm long, sometimes 1–2-bracteolate; inflorescence bracts 9–10, 0.5–1.2 cm × 3–7 mm, elliptic, rounded, the outer ones often becoming reflexed, pubescent without at the base, otherwise glabrous, yellowish; head 5–6 mm in diameter.
Fruits 1.7–2 × 1.5 cm, ellipsoid, ± smooth, yellowish-green, later turning yellow or reddish. Pyrenes 3(4), 1–2.5 cm × 8–9 mm × 5–6 mm, shallowly carinate, slightly apiculate at the apex, ± truncate at the base, lateral lobes smooth, entire.
Male flowers: calyx lobes 4–5, 1 mm long, truncate, pubescent at the apex; stamens 4, filaments 1 mm long, flattened, anthers 0.5 mm long, yellow; pistillode 1 mm high, cylindric-obconic, densely pubescent.
Leaves petiolate, the petioles (0.3)1–2(6.5) cm long, usually fairly slender, densely pubescent to glabrous.
