Characteristics

Shrubs up to 2.7 m tall with, long wand-like branches; twigs terete to subquadrate, shortly tomentose. Stipules interpetiolar, short, broad, auriculate, the auricles with the texture and colour of the leaves. Leaves opposite and decussate, varying in size even on the same branch; blade dark green, shiny and glabrous above, tomentose beneath with tawny or whitish substellate tomentum sometimes very shortly so, ovate-lanceolate to ovate-oblong or lanceolate to lanceolate-oblong, 2.8-12 cm long, 1-5 cm broad, acuminate to an acute apex, broadly cuneate or rounded at the base, margin finely serrate, sometimes entire and revolute, midrib and veins impressed above, prominent beneath; petioles deeply channeled, tomentose, 3-10 mm long. Panicles cymose, axillary and terminal; cymes several to many flowered, bracteate; bracts joined at the base, lanceolate-oblong, more or less boat-shaped; peduncles slender 2-8 mm long; pedicels very short or flowers subsessile. Calyx campanulate, shortly substellate tomentose, glabrous within, about 1.5 mm long; lobes subtriangular, a third to almost half of the calyx. Corolla 'whitish', white with orange throat, orange-yellow, lilac or 'salmon-coloured'; tube cylindric about 6 mm long, shortly and substellately tomentose without, sometimes partially glabrescent, glabrous within e x cept for some sparsely scattered hairs in the lower half; lobes subrotund, spreading to reflexed, up to about 1.5 m long and 1.5 mm broad, glabrous or tomentose at the base dorsally. Stamens inserted above the middle of the corolla tube; free portion of the filaments about as long as the anthers or shorter, adnate lower portion sometimes not distinguishable; anthers included. Ovary tomentose with short substellate hairs; style about as long as the ovary, glabrous at least in upper half, stigma terminal, clavate. Capsule substellate tomentose, glabrescent, more or less obovoid, splitting at the apex, exserted for a little more than half its length from the persistent calyx. Seeds several to many, attached to the free central placenta.

Stipules conspicuous, auriculate. Flowers: in axillary and terminal cymose panicles; stamens included; corolla ± 6 mm long, white with orange throat, orange-yellow, lilac or salmon-coloured; Apr.-Aug.
Leaves opposite, petiolate; petiole 3–11 mm. long, stellate–tomentose; stipules foliate, sometimes reduced to a line, elliptic or ovate or narrowly so, 2–5 times as long as wide, 2–13 x 0·5–5 cm., acuminate at the apex, cuneate or rounded at the base, serrate or sometimes entire and revolute at the margin, dark green, shiny, glabrous, almost bullate above, whitish–tomentose with short stellate hairs (often drying rusty) beneath; venation conspicuous, reticulate, much impressed above.
Pistil much shorter than the corolla tube, 2·2–4·3 mm. long; ovary subglobose or ovoid, laterally compressed, 0·9–1·5 x 0·7–1 x 0·6–0·9 mm., shortly stellate–tomentose, 2–celled; style included, stellate–tomentose at the base, 0·5–1·7 mm. long; stigma large, clavate or sometimes capitate, 0·3–1·2 x 0·3–0·5 mm.
Shrub, up to 2.7 m high. Leaves distinctly petioled, rounded or auneate at base, shiny and glabrous above. Stipules conspicuous, auriculate; petiole bases not prominent. Corolla tube long, cylindrical; stamens included. Flowers whitish, white with orange throat, orange-yellow, lilac or salmon-coloured.
A shrub or tree. It grows 4 m high. The leaves are shiny and deep green above and silver underneath. The flowers are small but occur in large spikes. They are cream or orange and have a sweet smell. The fruit is a small capsule that splits when ripe.
Stamens included, inserted at 2–2·5(–3·5) mm. from the corolla mouth; filaments short, 0·3–1 mm. long; anthers oblong or nearly so, 0·9–1·2 x 0·3–0·4 mm., rounded or obtuse at the apex, deeply cordate at the base, glabrous; cells parallel.
