Hakea is an Australian genus of trees and shrubs characterised by the production of persistent woody fruits that do not open to release their seeds until the death of the bearing branch from fire or other causes. Mature fruit size is correlated with the length of time the plant may retain the fruit before release (Groom & Lamont 2004). Many Hakea species have notably spiny leaves.
A number of species are grown as ornamental plants, and some have become invasive weeds in South Africa and New Zealand. These include the silky hakea or needle bush Hakea sericea, a native of south-eastern Australia which has rigid needle-like leaves about six centimetres in length. Kodjet Hakea laurina is a species found in southwestern Australia with flat leaves tapering to a blunt point and bearing red and cream, globular flowers.
Characters (from Harden 2001): Shrubs or small trees. Leaves flat with similar surfaces or terete, and then entire or divided into segments, or rarely trigonous. Conflorescences axillary, raceme-like with paired flowers, or in several- to many-flowered clusters, and then flowers not regularly or obviously paired. Flowers zygomorphic. Perianth tube revolute and curved under the limb; tepals splitting to base or remaining fused and splitting on upper side only, becoming free. Anthers 4, sessile. Hypogynous glands fused, horseshoe-shaped, obovoid or rarely disc-shaped, rarely absent. Ovary shortly stipitate, glabrous; ovules 2; style longer than the perianth, curved and protruding from a slit in the perianth before being released; pollen presenter an oblique or lateral disc or an erect cone. Follicle woody, surface smooth, wrinkled, blistered or warty, sometimes prominently beaked (apical portion of the fruit beyond the main swollen body of the fruit), often with apical horns (pair of hard points just behind fruit apex, often broken off in mature fruit); secondary thickening formed by the cambium, the fruit opening in 2 valves; seeds 2, compressed, testa expanded into a wing, usually at one end; seeds generally placed near the upper suture of the fruit and mostly borne in more or less same direction as stalk of fruit.
