Leaves opposite or ternate, often bright red when young; leaf-lamina 0·6–12 × 0·5–4·5 cm., broadly rounded-elliptic to narrowly elliptic or rounded-diamond-shaped, rounded to acuminate at the apex, the actual tip blunt or emarginate, rounded to cuneate at the base, glabrous or minutely puberulous, pale beneath with the close reticulate venation characteristically darker and forming a conspicuous pattern; midrib often reddish, impressed above, prominent beneath; petiole 2–9 mm. long, reddish.
Inflorescences 1·5–7·5 cm. in diameter, globose or pyramidal, usually many-flowered; branches often puberulous; pedicels very short or up to c. 1 mm. long; bracts 1·5–6 × 1–3·5 mm., very deciduous or rarely persistent, thin veined, ovate or oblong, cucullate, pubescent, those enveloping a triad of flowers or single terminal flower, larger than the secondary bracts, 1–3·5 × 1–2 mm., enveloping lateral flowers of the triad.
Petals 2·3–5 × 1–2·5 mm., yellowish-cream, white, pink, or crimson, often white at first and becoming red later, linear-oblong to distinctly obovate-spathulate, rounded or very slightly emarginate at the apex, always narrowest towards the base, mostly glabrous but usually pubescent towards the base inside.
Shrub, small tree or less often a large tree, mostly (0·9)4–16 m. tall but occasionally said to reach 27 m., evergreen; often a small gnarled bushy tree in exposed rocky places; bark grey, smooth or rough, sometimes slightly peeling or flaking, often fissured; blaze white with reddish or purplish border.
Calyx-tube and combined receptacle 2·5–7 mm. long, more or less cylindrical when mature, somewhat narrowed to the base, mostly crimson, glabrous or puberulous, minutely lobed or undulate at the apex.
Fruit 0·5–1 × 0·5–1 cm., pink or dull crimson, globose or ovoid, usually speckled with pale lenticels, rather woody inside, marked by the circular scar remaining after the calyx-tube has fallen off.
Branchlets reddish when very young, later pale, mostly squarish, which together with the characteristic leaf venation renders sterile twigs easily identifiable.
Seeds 2·5–3 × 2·5–3 mm., subtrigonous-ovoid, brown, minutely shagreened.
Scales 0·5–1·5 × 0·5–1·25 mm., yellow becoming crimson-pink.
Flowers sweetly scented.
A shrub.
