Characteristics

Small much branched densely leafy tree, 1.5–5 m. high; branchlets slender, twiggy, buff-coloured with persistent petiole bases, ultimate ones, at least pubescent with brown ascending hairs.. Leaves subsessile; lamina very small, subcoriaceous, oblong, elliptic or rarely ovate-orbicular, 0.9–2.5 cm. long, 0.4–1.2 cm. wide, rounded to acute, cuneate or rarely rounded at the base, with the midrib and margin very sparsely hirsute, otherwise glabrous, venation indistinct.. Cyme terminal, 1–5-flowered.. Flowers small, 5-merous, scarcely 2 mm. long.. Calyx-lobes suborbicular, ciliate.. Corolla-lobes thick, cucullate, oblong-deltoid, subequal to the tube, with dense hairs forming a ring at the base.. Stamens included, inserted just above the base of the corolla-tube; filaments short; anthers glabrous.. Ovary ovoid, glabrous; style very short or absent, glabrous.. Fruit globose, 8–9 mm. in diameter, with a thin skin, red.. Seed flattened, disk-like, 7–8 mm. in diameter.
More
Leaves small or very small, subsessile or shortly petiolate; petiole 0·2–1(2) mm. long; pubescent with brown ascending hairs, lamina paler beneath, subcoriaceous, very variable in shape and size, ovate, narrowly ovate, elliptic, narrowly elliptic, obovate, or sometimes suborbicular, (1)1·5–4(5) times as long as wide, (4)6–20(27) x 3–8(11) mm. in the continent, rounded to acute or broadly and bluntly acuminate at the apex, cuneate or rounded at the base, glabrous or with ranked appressed short hairs on the costa above, beneath sparsely pubescent or with some hairs at the base and often also on the costa, often minutely ciliate above; with one pair of not very conspicuous secondary veins from or from above the base curved along the margin and often with a faint submarginal pair; margin more or less revolute, especially in old leaves.
Corolla in the mature bud 2·8–3·3 times as long as the calyx, 2·2–4 mm. long, white, outside glabrous or minutely papillose–pubescent, inside white–penicillate in the throat; tube campanulate to nearly cylindrical, 1·2–1·9 times as long as the calyx, 0·8–1·4 times as long as the lobes, at the throat 1·2–1·5 mm. wide; lobes narrowly triangular, 1·5–2 times as long as wide, 1·2–1·8 x 0·8–1 mm., acute, erect or suberect.
Sepals connate at the base up to one–third of their length, equal or subequal, broadly ovate to suborbicular, 1–1–2 times as long as wide, 0·8–1·2 x 0·8–1·2 mm., obtuse to acute at the apex, distinctly ciliate, glabrous on both sides, without colleters.
Inflorescence terminal and (occasionally) also axillary, lax or rather lax, few–(sometimes l)–flowered, 5 x 3–15 x 10 mm., 0–2 x times branched. Peduncle and branches pubescent with brown ascending hairs, especially at the base.
Branches pale brown, not lenticellate, with the bark peeling off, not sulcate, often dichotomously branched; branchlets slender, pubescent with ascending brown hairs, terete or nearly so, not sulcate when dry.
Fruit red or orange, small, soft, globose or laterally compressed (?), about 8–9 mm. in diam., 1–seeded, with somewhat granular skin, slightly shining. Wall thin. Pulp red or orange.
Stamens included; filaments very short, inserted on the middle of the corolla tube; anthers circular or oblong, 0·5–0·9 x 0·5–0·7 mm., ciliate at the base or sometimes all around.
Pistil glabrous, very short, 0·9–1·4 mm. long; ovary ovoid, 0·8–1 x 0·6 mm., 2–celled; style very short, up to 0·6 mm. long, or none; stigma capitate.
Seed ochraceous–brown, flattened, disk–like, elliptic, 8 x 7 x 1·5 mm., rough, with thick very short erect hairs, slightly dented at one side.
