Genus Cordyline Family Asparagaceae

Description: Erect or sprawling glabrous shrubs to 5 m high; stems woody with annular scars when young.

Inflorescence a terminal or lateral panicle. Flowers actinomorphic, bisexual. Tepals fused at base, bluish to mauve or white. Stamens 6; filaments inserted at base of perianth. Ovary superior; ovules 2–16 in each loculus; stigma capitate or 3-lobed.

Flowering: Flowers are often described as sweet–scented, but information is not available for all species in N.S.W.

Distribution and occurrence: World: c. 20 species, tropical & subtropical regions, chiefly Asia to New Zealand, but also Africa & South America. Australia: 9 native species (8 species endemic), Qld, N.S.W. One naturalised species, C. australis.

C. congesta, C. petiolaris and C. rubra were previously included in C. fruticosa (L.) A. Chev. s. lat. C. fruticosa s. str. is native to N Qld, Malesia and Pacific islands but has been cultivated more widely by humans than its original distribution would have been in this region. This genus has often been included in the Agavaceae.
