Much-branched, erect to spreading, up to c. 2 m. tall; branchlets glab. to sparingly setose. Lvs opp. or subopp., sessile or subsessile, sts ± amplexicaul. Lamina thick, coriac., glab., dull green above, paler below, ± 3-6 × 2-3 cm., cordate to subtruncate at base, about ovate-oblong, subacute, mucronulate; margins crenate-serrate, teeth apiculate. Fls in terminal and subterminal oppositely branched racemes 5-10 cm. long, forming ample panicles. Pedicels pubescent, up to c. 5 mm. long; bracteoles ovate, obtuse, c 2.5 mm. long. Calyx deeply cut; lobes ovate triangular to ovate-oblong, c. 1 5 mm long, margins ± ciliolate. Corolla glab. or rarely ± pubescent within, urceolate, 2-3 mm. long; lobes slightly recurved; anther-cells conspicuously 2-awned; filaments expanded towards base, abruptly contracted to insertion. Capsule c. 3-4 mm. diam., surrounded by dry, not enlarged, calyx.

A large shrub, 1 to 3 metres high. Branchlets without pubescence or setae. Leaves opposite, 25-60 × 15-30 mm, length seldom more than twice the width, sessile or almost so, cordate, ovate or ovate-oblong, very thick and coriaceous, mucronate at the obtuse apex, margins slightly thickened, bluntly serrulate, teeth mammilate, upper surface with or without a fine pubescence along the midrib together with a few bristles (or their bases in older leaves), otherwise glabrous and glossy, lower surface densely strigose, especially on the veins of young leaves, only the hair bases remaining on older leaves. Inflorescence of axillary and terminal racemes, the latter often compound forming broad terminal panicles with opposite spreading branches. Peduncle and pedicels glabrous. Corolla glabrous within.

Much-branched, erect to spreading shrub, up to c. 2 m tall; branchlets glabrous to sparingly setose. Lvs opposite or subopposite, sessile or subsessile, sometimes ± amplexicaul. Lamina usually 2.5-6 × 1.5-3 cm, lanceolate-ovate, elliptic-ovate, broadly ovate, or suborbicular, thick, coriaceous, glabrous, crenate-serrate or serrulate; base cordate to subtruncate; apex subacute, mucronulate. Fls in terminal and subterminal oppositely branched racemes 5-10 cm long, forming broad panicles; pedicels to c. 5 mm long, glabrous; bracteoles ovate, c. 2.5 mm long. Calyx lobes ovate-triangular to ovate-oblong, sharply acute or acuminate, c. 1.5 mm long. Corolla urceolate; tube 2-3 mm long; lobes triangular-ovate. Capsule c. 3-4 mm diam., surrounded by dry calyx.
