原生地・分布（英語）:

説明（英語）: Genus of 11 species of evergreen shrubs and small trees found in moist forest in Australia, often at high altitudes. They have crowded branches with spiralling, alternate, narrow leaves, overlapping at the bases. The small, ovoid to conical or bottle-shaped flowers are borne in terminal spikes or panicles; they are open at the bases and almost closed at the tips, quickly losing their petals and leaving the stamens and stigmas .exposed. In frost-prone areas, grow half-hardy and tender species in a cool greenhouse or conservatory. In frost-free areas, grow the shrubby species at the base of a warm, sunny wall or in a shrub border; use the trees as specimen plants.

耐寒性（英語）: Frost hardy to half hardy.

栽培（英語）:

繁殖（英語）: Surface-sow seed in containers outdoors, ideally as soon as ripe or in spring (germination is unreliable). Root semi-ripe cuttings with bottom heat in late summer.
