Characteristics

Shrub or small tree to 9 m. tall, sometimes more; young branches glabrous or finely pubescent at first.. Leaf-lamina coriaceous, elliptic to oblong or oblanceolate, 5.5–30 cm. long, 2.4–12 cm. wide, the base cuneate to ± subrounded, the apex subobtuse, acute or sometimes shortly acuminate, glabrous or pubescent on the midrib beneath; margin serrate to subentire; lateral veins 8–12 pairs, prominent; petiole (0.5–)l–4.6(–6) cm. long, glabrous, rarely pubescent.. Inflorescence a stout terminal thyrse, very rarely lateral; rachis 7–16.5(–20) cm. long, finely pubescent; flowers yellow, greenish yellow, greenish white or white, erect at anthesis; bracts and bracteoles lanceolate to triangular, 2–3 mm. long, pubescent, persistent; peduncle 12–30 mm. long, finely pubescent; pedicels 1–3 mm. long, finely pubescent.. Sepals ovate to oblong, 2–4 mm. long, faintly ribbed or smooth, usually finely pubescent, the margin ciliate.. Petals ovate-lanceolate to oblong, 4–6 mm. long, acute to subobtuse, scarcely recurved at the tip, glabrous or pubescent on the exterior.. Stamens 3.5–4 mm. long; filaments united into a tube, with or without a short, free, lobed margin; connective-appendage triangular-ovate, ± acute, not decurrent; thecal appendage solitary, very short or absent.. Ovary glabrous; style ± 3 mm. long.. Capsule woody, unlobed, 15–25 mm. long, rugose, glabrous; pericarp thick, 1.5–2.5 mm.
More
Leaves petiolate; lamina 9–24 x 4–9 cm., ± deflexed, oblong to elliptic or oblanceolate, acute (rarely acuminate) to rounded at the apex, cuneate at the base, subentire or sinuate to serrate or shortly spinose, rather coriaceous, glabrous, with prominent venation on both surfaces, eglandular; petiole (10) 20–55 (60) mm. long, channelled above, glabrous; stipules soon caducous.
Stamen-tube with or without a short free 5-lobed margin, glabrous or occasionally pubescent; anthers sessile, inserted opposite the lobes of the stamen-tube, ovate-truncate, glabrous or occasionally pubescent, with a triangular-ovate, acute, not decurrent, connective-appendage, with or without a single, short, lanceolate, thecal appendage.
Petals 4–5 mm. long, 11/2–2 times as long as the sepals, white to greenish-yellow, ovate-lanceolate, acute or obtuse, scarcely recurved above, equal, ± pubescent.
