A small straggly tree which loses its leaves during the year. It grows 2-5 m tall. It has a short stem and spreading crown. The bark is smooth and grey. The leaves are simple and alternate. The leaves are broadly oval and 2.5 cm long. They are leathery and borne close together near the ends of twigs. The flowers are pale pink. They are 7 mm across. The occur in clusters in branches. The fruit are round and orange to red. They are small and cherry like and in clusters. The seed are oval, brown, hard and fibrous. The fruit are edible.
Lamina 1.2–4.0(8.0) x 0.5–2.5(4.0) cm., obovate or sometimes varying from ovate to oblanceolate, sometimes shortly hispid on both surfaces, more often glabrous except by some rigid acroscopic appressed hairs on the margin or quite glabrous, apex rounded or rarely subacute, base narrowly tapering into a short petiole, margins entire, papery to leathery, with 3–4 secondary nerves on each side of the midrib, usually not prominent, sometimes hardly perceptible, often with sparingly pilose acarodomatia at the axils.
Small tree or shrub, 0.8-6.0 m high. Leaf margins always entire; lamina glabrous to shortly hispid; acarodomatia present; petiole absent or up to 4 mm long, rarely up to 8 mm long. Corolla lobes as long as or shorter than tube, ± spreading. Flowers mauve to pale blue or white.
Flowers hermaphrodite, 5-merous, arranged in corymbs 1–3(4) cm. long, usually few-flowered, sessile or shortly pedunculate, puberulous or shortly hispid, terminal on the shoots or on the short-shoots; pedicels 0.2–2.0(4.0) mm. long.
Many-stemmed shrub or small tree to 6 m, branches drooping and tangled. Leaves usually clustered on short shoots, obovate, margins densely ciliate. Flowers mauve to pale blue fading whitish. Fruits subglobose, orange-red.
Corolla mauve to pale blue or white or, a few times purple; tube 3–4(6) mm. long, cylindrical or narrowly funnel-shaped, glabrous; lobes 2.5–4.0 x 1.5–2.0 mm., ovate to oblong, rounded at apex, ciliate, spreading.
Calyx 1.5–2.5 mm. long, variably lobed from above middle to near base, pubescent to subglabrous outside and inside; lobes narrowly triangular to oblong, acute to rounded at apex, ciliate.
A small tree up to 6 m. high or more often a many-stemmed shrub 0.8–4.5 m. high, deciduous; branches glabrous, light-grey to dark-grey.
Leaves arranged either alternately on long juvenile shoots or crowded at the ends of short shoots, these sometimes only vestigial.
Fruit c. 5 x 7 mm., fleshy, glabrous, orange to red when ripe; pyrenes 4 with the out surface irregularly reticulate-foveate.
Ovary glabrous; style 4.0–6.5 mm. long, divided 1/52/5-way down; stigmas truncate, sometimes umbilicate.
Anthers 1.0–1.5 mm. long, sagittate-oblong; filaments 2.5–3.5(5.0) mm. long, slender.
Petiole up to 0.4 cm. long or absent, very rarely up to 0.8 cm. long.
