 Description

Bushy shrub to 2.5 m tall. Stems erect, eglandular-puberulent or -pubescent; hairs usually uniform, rarely bifarious, sometimes sparse. Leaf bud distinct, its leaves appressed at margins until fully grown; sinus absent. Leaves opposite-decussate, erecto-patent to spreading; lamina sub-coriaceous, narrowly oblong to oblong-lanceolate, 16–44 mm long, 2.5–9.0 mm wide, dull, green or pale green above and beneath; midrib and often two lateral veins evident; surfaces glabrous or with sparse, fine, eglandular hairs along midrib and near base above, sometimes hairs short and glandular; margin scabrous, ciliate, or pubescent, entire; apex obtuse to acute, sometimes weakly plicate-acuminate; base cuneate; petiole indistinct, broadly winged, 1–3 mm long. Inflorescence a lateral raceme, 23–73 mm long; flowers crowded, 34–72, female or bisexual on separate plants, ⚥ > ♀; bracts alternate or loosely whorled, lanceolate to ovate, < pedicels; pedicels erecto-patent to spreading, 0.8–3.0 mm long, puberulent all around. Calyx lobes usually 4, sometimes 5 (5th lobe small, posterior), obtuse to sub-acute, 0.8–1.5 mm long, equal, usually mixed glandular- and eglandular-ciliolate or rarely glandular-ciliolate. Corolla 4–7 mm diameter; tube white, 2.5–4.5 mm long, >calyx, eglandular-hairy inside; lobes 4, white or tinged purplish or pink at anthesis, erecto-patent to spreading or recurved, unequal, elliptic to obovate, 2–3 mm long, obtuse to rounded; nectar guides absent. Stamen filaments white, 2.5–3.3 mm long; anthers pink or magenta. Style glabrous, 4–7 mm long. Capsules latiseptate, sub-acute to obtuse, glabrous, 3.5–5.5 mm long, 1.8–4.0 mm at widest point. Seeds ellipsoid, ovoid, or oblong, flattened, smooth, brown, 1.3–2.4 mm long.
