Hakea polyanthema is a shrub of the genus Hakea native to Western Australia.

Description

The dense multi-branched shrub typically grows to a height of 1 to 2 metres (3.3 to 6.6 ft) with hairy branchlets. The glabrous leaves are arranged alternately with a blade that is 20 to 60 millimetres (0.8 to 2.4 in) in length and 1 to 1.5 mm (0.039 to 0.059 in) wide. It blooms from August to September and produces white flowers. The axillary inflorescences have a hairy perianth that is 5 to 7 mm (0.20 to 0.28 in) in length.[1] The erect ovate shaped fruit are 25 to 35 mm (0.98 to 1.38 in) in length and 1.5 to 1.9 mm (0.059 to 0.075 in) with a corky texture and no beak . the seeds within are around 25 mm (0.98 in) in length with a wing surrounding the seed's body.[2]

Taxonomy

The species was first formally described in 1904 by Ludwig Diels as part of the work by Diels and Ernst Georg Pritzel entitled Fragmenta Phytographiae Australiae occidentalis. Beitrage zur Kenntnis der Pflanzen Westaustraliens, ihrer Verbreitung und ihrer Lebensverhaltnisse. Botanische Jahrbucher fur Systematik, Pflanzengeschichte und Pflanzengeographie.[3]

The name of the species is taken from the Greek words poly- meaning many, and anthemon meaning flower. This is thought to be in reference to the apparent density of the flowers.[2]

Distribution

It is native to a small area on the west coast in the Mid West and the Wheatbelt regions of Western Australia between Geraldton and Dandaragan on sandplains where it grows in sandy soils[1] as part of shrubland communities.[2]
