Decaspermum J.R.Forst. & G.Forst.

Erect shrubs or trees. Branchlets sparsely sericeous to villous or (not in Australia) glabrous. Leaves opposite, petiolate; lamina glabrous to variously hairy, with oil glands (punctate), pinnately veined, intramarginal vein present, lateral veins obscure or invisible below. Inflorescence axillary or terminal, metabotryoids or botryoids, solitary or paired, sometimes paniculate. Flowers bisexual or (not in Australia) sometimes staminate, 3–5-merous, often fragrant; petals white to cream or (less so in Australia) pink, punctate; hypanthium cupulate (globose, urceolate or obconiform, fide Scott 1979, Chen & Craven 2007), sericeous. Calyx lobes persistent. Stamens numerous, in several series; filaments filiform; anthers globular, dorsifixed, dehiscing by longitudinal slits, connective usually terminating in a gland. Ovary ± inferior, 3–12 (13)-locular, placentation axile; ovules (1) 2–4 per locule, collateral. Stigma apex usually capitate or peltate. Fruit a berry, ± globose or subglobose, often vertically ribbed. Mature seeds in each locule collectively encapsulated by membranous tissue from ovary wall (often described as the seeds in each loculus being separated by a vertical false septum); testa hard.

Some species cultivated as ornamental or hedge plants, e.g. Decaspermum humile for its shiny green foliage, often weeping habit, fragrant flowers and edible berries.
