Shrub or tree to around 25 m high, usually dioecious, or occasionally apparently male plants producing some fruit. Leaves aromatic, clustered at branch-tips, ovate to oblanceolate, 6–17 cm long, 2–5 cm wide, glossy above, minutely pubescent when young, margins usually undulate. Flowers sweet-scented, in terminal umbel-like cymes on 1–several branches 1–2.5 cm long; pedicels 2–14 mm long; calyx 5–10 mm long, divided to near midway into 5, recurving, often unequal lobes, splitting to base along 1 or 2 lines; petals oblanceolate, creamy-white, recurved apically. Male flowers with corolla 12–18 mm long, narrower than in female flowers, anthers exserted from throat, filaments thick, white, hairy ovary and style ca. same length, stigma slightly knobby; ovules few. Female flowers 12–14 mm long, staminodes present; stigma plump, capitate, lobed; ovules numerous. Capsule globose to obovoid, 8–13 mm long, 10–15 mm diam., orange to yellowish-brown, glabrous; inner face smooth, yellowish; seeds numerous, 3–4.5 mm long, brownish-red.

Originally it grew in moist areas on the Australian east coast, where its natural range was from south-east Queensland to eastern Victoria, in lowland forests and woodlands in river valleys and near-coastal sites. Currently it has become invasive in parts of Australia where it is not indigenous. It is also highly invasive in South Africa, the Caribbean, Hawaii, the Azores and southern Brazil.

It flowers from the end of winter to the beginning of summer. Occasionally hybridises with Pittosporum bicolor forming the hybrid Pittosporum bicolor × Pittosporum undulatum.
