Hakea ivoryi , commonly known as Ivory's hakea,[2] corkwood or the corkbark tree,[3] is a shrub or small tree in the family Proteaceae and is endemic to an area in the South West region of Queensland and the north west of New South Wales.[4]
Description
[edit]Hakea ivoryi is shrub or small tree typically grows to a height of 2 to 12 metres (7 to 39 ft) with white flat silky hairs becoming smooth along branchlets and forms a lignotuber. It has simple needle-like leaves 3 to 18 centimetres (1 to 7 in) long with silky hairs becoming hairless with age. Young trees often have highly divided segmented leaves. The bark is brown, rough and corky. The inflorescence consists of 20–50 white-cream flowers on a short stem and appear in leaf axils from October to January. The fruit are smooth, egg-shaped 25–35 mm (0.98–1.4 in) long and 10–15 mm (0.4–0.6 in) wide ending with a short beak.[4][5]
Taxonomy and naming
