A small to medium-sized tree 5-15 m in height. Bark: pale to dark grey, cracked, roughish; young branchlets usually hairless, blackish. Leaves: alternate, elliptic, 2.5-7 x 1.5-3.5 cm, leathery, hairless, glossy dark green above, paler with 5-7 pairs of lateral veins slightly prominent below, midrib flat above and prominent below, drying to brown or blackish; apex rounded to attenuate into an abrupt slender point; base tapering; margin entire, tightly wavy; petiole 2-5 mm long. Flowers: white, male flowers in 2-to 7-flowered cymes; female flowers in small, axillary, 2-to 3-flowered clusters (Nov.-Mar.). Fruit: narrowly ellipsoid, sharply pointed, up to 2 x 1.2 cm, purplish black, persistent calyx with 3 lobes about 0.7 cm long at the base, in groups of 2 or 3 in the leaf axils (Jun.-Oct.). Seeds: 1, obovoid, black, smooth.
Leaves subcoriaceous, drying pale brown or blackish; lamina up to 7 x 3·6 cm., narrowly or broadly rhombic–elliptic, apex usually subacuminate, rarely acute, the tip itself usually slightly emarginate, base cuneate, margin, both in living and dried leaves, conspicuously undulate; lower surface glabrous; lateral nerves in 5–7 pairs, slightly prominent beneath; tertiary nerves and veins scarcely visible; petiole about 0·2 cm. long.
Fruits subsessile, solitary or 2–3 together in the axils of fallen leaves on second and third year branchlets, up to 2 x 1·2 cm., glabrous, fusiform, apiculate, style persistent.
Calyx 0–2 cm. long, with 3 narrowly deltate, acute lobes, 0·15 x 0·15 cm., glabrous outside except for the sparsely setulose margin, glabrous inside.
Male flowers axillary and ramuligerous, in contracted 7–12–flowered cymes; peduncle 0·1 cm. long; pedicels 0–1–0–2 cm. long, glabrous.
Fruiting calyx usually c. 0·7 cm. long, glabrous, tube longer than the lobes, gradually narrowed to the pedicel; lobes ovate–deltate.
Stamens 5–11, exserted, up to 0·5 cm. long; anthers 0·1–0·15 cm. long, lanceolate, obtuse, densely setulose.
Corolla subrotate, 0·6 cm. long, glabrous; tube 0·15 cm. long; lobes 3, 0·45 x 0·3 cm., apex obtuse.
Bark dark grey, rough but less so than in D. quiloensis.
Seed 1, obovoid, 1·1 x 0·6 cm., black, endosperm smooth.
Evergreen shrub or tree up to 20 m tall.
Pistillode 0·1 cm. long, glabrous.
