Hakea hookeriana, commonly known as the Barren Range hakea,[2] is a shrub of the genus Hakea native to Western Australia.

Description

The erect open non-lignotuberous shrub or tree typically grows to a height of 1 to 5 metres (3.3 to 16.4 ft). The branchlets can be either glabrous or hairy and ferruginous[3] The narrow obovate leaves are 7 to 13 centimetres (2.8 to 5.1 in) long and 10 to 25 millimetres (0.4 to 1.0 in) wide.[4]

It produces red brown[3] or white or cream-yellow flowers from September to January.[4] Each inflorescence is umbelliform containing five, seven or nine flowers with obscure rachis. After flowering obliquely obovate shaped fruit that are 5 to 5.5 cm (2.0 to 2.2 in) long and 2.7 to 3.3 cm (1.1 to 1.3 in) wide are formed. Within the fruits are obovate shaped seeds with a wing down a single side.[4]

Hakea hookeriana is found in an area in weastern part of Fitzgerald River National Park along the south coast of the Goldfields-Esperance region of Western Australia where it is found among rocks and rocky outcrops on cliffs and gullies growing in quartzite soils.[3] It is often part of scrubland communities including Banksia heliantha.[4]
