Characteristics

Shrub or subshrub (0.1–)0.2–6 m. tall; stems glabrous to densely velvety pubescent, sometimes with yellow-brown hairs, the older stems often becoming glabrescent or glabrous.. Leaf-blades narrowly to broadly elliptic, elliptic-obovate, ± ovate or oblong-elliptic, 2–18 cm. long, 0.5–9 cm. wide, rounded to acute or ± acuminate at the apex, cuneate at the base, glabrous or densely velvety pubescent above and beneath or sometimes with only rather sparse long hairs on the midnerve beneath, mostly rather thin but sometimes ± coriaceous, the margins often thin, drying yellow and sometimes very marked, sometimes wavy; domatia absent; nodules numerous, spot-like or rarely linear, scattered in the lamina; petiole 0.1–2.5 cm. long, glabrous or pubescent; stipules usually brown and ± scarious, ovate-triangular, 2.5–11 mm. long, bilobed at the apex, the lobes acuminate or filiform, 0.5–4(–6) mm. long, glabrous to densely pubescent.. Flowers heterostylous, 5(–6)-merous, in panicles or umbels or collections of umbels, 1–14 cm. long, the actual component parts often quite dense; peduncles 0.5–9 cm. long, glabrous to densely pubescent; secondary branches 0.2–2.5 cm. long, similarly hairy; pedicels 1–3(–6 in fruit) mm. long, glabrous or hairy; bracts and bracteoles small, filiform or narrowly triangular, up to 4 mm. long.. Calyx glabrous or hairy; tube 0.5–1 mm. tall; limb cupuliform, 0.75–1.5 mm. long, glabrous or hairy; lobes 0.2–0.75 mm. long or ± obsolete.. Corolla white, cream, greenish or rarely yellow, glabrous outside; tube 2.5–6 mm. long; lobes oblong or elliptic, 2–3(–5) mm. long, 0.8–1.2 mm. wide.. Stamens with filaments 1.5–3 mm. long in short-styled flowers, 0–0.5 mm. long in long-styled flowers.. Style 1.5–3.75 mm. long in short-styled flowers, 3.5–6(–10) mm. long in long-styled flowers; stigma-lobes 0.25–0.75(–2) mm. long.. Drupes red, with 2 pyrenes, subglobose, 5–7 mm. diameter or didymously subglobose, 7–8 × 4–6 mm., glabrous or sparsely hairy when young; pyrenes semiglobose, 4–4.5 mm. diameter, 3 mm. thick, slightly rugulose.. Seeds semiglobose, similar in size, ventral face with a T-shaped median fissure but rest of albumen not ruminate.
