Leaf blades 6.3–17 × 2.3–8 cm, elliptic to broadly elliptic, occasionally oblong-elliptic, or sometimes narrowly elliptic, acute to acuminate at apex, acute to obtuse at base, glabrous on upper surface, often with stiff hairs on the midrib beneath or scabrid-pubescent in a band on either side of midrib or all over lower surface, stiffly papery to subcoriaceous; midrib straw-coloured, crested above, prominent below; lateral nerves in 5–7 main pairs; tertiary nerves reticulate, usually apparent on both surfaces; domatia often present; petioles 2–9 mm long, channelled above, glabrous or with a few stiff hairs; stipules 0.4–3.5 cm long, 2.25–6(7) mm wide at base, narrowly triangular, triangular-linear, acute or acuminate, or sometimes abruptly narrowing to a linear lobe, often becoming subulate at top, mid-nerve apparent.
Inflorescences borne at the top node or the next 1–3 nodes down, 1–9-flowered, forming narrow compact panicles occasionally with branches discernible when mature, sessile or with a peduncle not exceeding 3 mm long; pedicels up to 5 mm long; bracts/bracteoles 4–9 mm long, lanceolate, often ciliate.
Calyx glabrous except for the ciliate lobes; tube 2–5 mm long; limb-tube 1.75–2.5 mm long, slightly wider than tube; lobes 2–3.5(5) mm long, triangular at base, subulate above.
Anthers mostly exserted, with fine apiculum, 0.3–0.6 mm long, often reflexing at apex, shortly hastate at base.
Fruit brownish when dry, 2.9–4.5 × 1.1–1.8 cm, ellipsoid to spindle-shaped; calyx limb persistent.
Corolla glabrous; tube (5.8)7.2–11.2 × 0.17–0.22 cm; lobes 1.2–3 × 3–5 mm, oblong, acuminate.
Shrub 1–4 m tall; young branches sometimes grooved, glabrous.
Pollen presenter 4–5 mm long, spindle-shaped, acuminate.
Seeds rusty-brown, 7–8 mm long, strongly striated.
