Tree or shrub up to 25 m. tall; young stem very shortly appressed-pubescent, glabrescent (one-year-old stem glabrous).. Leaves petiolate, petiole 6–15 mm. long, glabrous; blade varying from narrowly elliptic to almost broadly oblong and elliptic-lanceolate to broadly elliptic, up to 11.5 × 6 cm. or 14 × 5 cm., rounded or cuneate to an acute base, rounded to acuminate or very rarely cuneate to an obtuse or acute apex, margin entire or shallowly sinuate or bluntly and shallowly serrate especially above, glabrous.. Flowers numerous; pedicels 1.5–4 mm. long, glabrous, articulate medially or above.. Calyx 4–5 or 5–6 (rarely 7 [–8])-fid; tube 2–3 mm. long, lobes 1 mm. long, semi-circular to deltoid, apex obtuse (to acute), glabrous.. Stamens 8–10 or 10–12 (–14), inserted on the ± lobed disc.. Ovary superior to partly inferior, very usually 2-celled (very rarely 3-celled), glabrous, ± sparsely pilose above the middle, to regularly pubescent or densely white-hirsute especially above the middle.. Capsule ellipsoid or subspherical to obovoid, up to 7 mm. long, glabrous or shortly pubescent.
Tree, 3-25 m high, evergreen; branches terete; bark brownish, smooth, lenticels scattered, raised. Leaves decussate, nodes thick; ± 140 x 75 mm, elliptic-lanceolate, leathery, glabrous, base tapering, apex broadly tapering, margins entire; petioles short, thick. Inflorescences dense and congested fascicles. Flowers 4-6-merous; pedicels short, articulate at or above middle. Calyx glabrous; tube elongate-campanulate; lobes semi-circular to deltate. Corolla: lobes linear-spathulate, laciniate at apex, white. Disc tubulous-campanulate, lobed. Stamens 8-12, inserted along and below disc margin; filaments 4.5-7.0 mm long; anthers ellipsoid. Ovary ± obovoid 2-or 3-locular; style longer than ovary; stigma slightly 2(3)-lobed. Flowering time Dec.-July. Fruit a round to ovoid capsule, up to 7 mm long, velvety or smooth, dehiscent. Seeds small, aril yellow.
Leaves decussate (sometimes verticillate) on thick nodes; leaf-lamina (10·5)12–15 x (4)5–7·5 or 5–14(21) x 3–5(10) cm., elliptic-lanceolate, narrowly to broadly elliptic or oblong or rarely ovate or obovate, glabrous, ± leathery; apex rounded to acuminate, obtuse or ± acute; margins entire, shallowly sinuate to bluntly and shallowly remotely serrate usually above the middle towards the apex; base rounded to cuneate, ± acute at its extremity; petiole (6)8–15(17) mm. long, thick, pubescent when young and glabrous with age; stipules 2–4 mm. long, ± triangular, thick, slightly puberulous to glabrous, soon caducous.
Ovary 1–1·5 mm. long, obovoid to ovoid, 2(3)-locular, glabrous, sparsely pubescent above the middle to regularly pubescent or densely white-hirsute mainly above the middle, superior or semi-inferior; style 3–6 mm. long, glabrous, slightly 2(3)-lobed.
Stamens 8–10(12) or (8)10–12 inserted along and outside below the margin of the tubulous-campanulate ± lobed disk; filaments 4·5–7 mm. long (the oppositipetalous longer than the alternipetalous); anthers 0·7–1·1 mm. long, ± ellipsoid.
Calyx glabrous; calyx-tube 2–4 mm. long, elongate-campanulate; calyx-lobes 0·5–1·5 mm. long, semi-circular to ± deltate, rounded or obtuse (rarely acute) and usually puberulous at the apex, suberect.
Tree (3)5–20(25) m. high, evergreen; branches terete, shortly appressed-puberulous to glabrescent when young, glabrous with age; bark brown or grey, smooth with scattered raised lenticels.
Flowers 4–5-or 5–6-merous; pedicels 1·5–4 mm. long, glabrous, articulate at or slightly above the middle; bracteoles minute, puberulous to glabrous, or absent.
Capsule up to 7 mm. long, ellipsoid, ± spherical to obovoid, glabrous or puberulous mainly above the middle.
Petals linear-spathulate, laciniate at the apex, white, glabrous, inserted outside at the base of the disk.
Inflorescences ± dense and congested fascicles.
Disk c. 1 mm. high, entire to ± deeply lobed.
