Small tree or shrub, up to 5 m high. The leaves are subsessile to distinctly petiolate, obovate-acute to narrowly obovate-acute, thick-textured, almost semisucculent, glossy green, glabrous or very rarely hairy. Domatia occur on the lower leaf surface. Round bacterial nodules are arranged mainly along the main and secondary veins but are sometimes more scattered over the leaf surface. The flowers are arranged in tight, unbranched, umbrella-like balls on short side branches. The calyx lobes are linear, 4-6 mm long and persistent in fruit. Flowering has been recorded from October to February. It grows in coastal bush on sand dunes, on hillsides, in forest and wooded kloofs. Distribution: only in the Eastern Cape..

P. cooperi Harv. & Sond. Pompon bride's bush; pompombruidsbos (Afr.); luphehlwane (Siswati); is-Anywana (Zulu). SA Tree No. 719.4

Domatia covered by dense hairy pockets occur in some of the axils of the main and secondary veins on the lower leaf surface. The bacterial nodules are round or slightly elongated, mostly arranged along the veins. The flowers are arranged in dense, many-flowered, unbranched balls on side branches. The calyx lobes are linear, hairy, 5-8 mm long and are persistent in fruit. Flowering has been recorded from October to January.
