Hakea commutata

Hakea commutata is a shrub in the family Proteaceae native to Western Australia. A variable species in shape and growing requirements, including mallee heath, sand and along creek lines.

Description

Hakea commutata is a lignotuberous straggly or dense rigid shrub with a rounded habit growing to high. Needle-shaped leaves are long and wide ending in a point long. Leaves are bluish-green with a whitish powdery covering, smooth or sparsely covered in coarse rough hairs and small protuberances. The inflorescence have 8–12 flowers either in leaf axils or at the end of branches.
The cream-white to yellow perianth is in length and tinged red at the base. The pistil is and has an oblique pollen presenter. Red-pink and cream-white flowers appear from September to November, occasionally into December. Woody brown finely wrinkled fruit are obliquely oval shaped long and wide. The black to dark brown seeds have a wing down one side and are long. The seed takes a mean time of 23 days to germinate.

Taxonomy

Hakea commutata was first formally described by botanist Ferdinand von Mueller in 1865 as part of the work Fragmenta Phytographiae Australiae. The only synonym is Hakea nodosa.
The specific epithet commutata is a Latin word meaning "with change" Mueller adopted the epithet falsely believing the leaves in this species were variable.

Distribution

It is endemic to an area in the Wheatbelt and Goldfields–Esperance regions from about Toodyay in the north to Fitzgerald River National Park in the south west and Cape Arid National Park in the south east. It is found along watercourses and among granite outcrops growing in sandy-loam or clay soils and is usually part of mallee heath communities or mallee communities over laterite.

Conservation status

Hakea commutata is classified as "not threatened" by the Western Australian GovernmentDepartment of Parks and Wildlife.
