Hakea elliptica, commonly known as the oval-leaf hakea, is a shrub of the genus Hakea native to Western Australia.

Description

The erect non-lignotuberous shrub typically grows to a height of 2 to 4 metres (7 to 13 ft).[1] The branchlets are covered with densely matted hairs that re reddish brown near flowering. The mature leaves are alternately arranged with an elliptic to broadly elliptic shape. the leaves are flat with a length of 4.5 to 9.5 centimetres (1.8 to 3.7 in) and a width of 1.5 to 5.5 cm (0.59 to 2.17 in).[2] It blooms from December to February and produces white-cream flowers.[1] The solitary inflorescences contain 35 to 40 flowers 35–40 flowers with cream-white perianth. Following flowering obliquely elliptic shaped fruit are formed that are 3 to 3.7 cm (1.18 to 1.46 in) in length and 1.8 to 2.2 cm (0.71 to 0.87 in) wide contining blackish-brown ovate seeds.[2]

Taxonomy

The species was initially described as Conchium ellipticum in 1807 by James Edward Smith in the work Conchium. The Cyclopaed, Smith then revised the name the following year as Conchium elliptica in A botanical sketch of the genus Conchium published in Transactions of the Linnean Society of London. Robert Brown reclassified the species to the Hakea genus in 1810 in the work On the natural order of plants called Proteaceae in the Transactions of the Linnean Society of London.[3]

The type specimen was collected from King George Sound in 1803 by A.Maxwell.[2]

The species name is from the Latin word for elliptic, referring to the shape of the leaves.[2]

Distribution

It is found in an area along the south coast in the Great Southern region of Western Australia between Denmark and just east of Albany where it grows in sandy soils over granite.[1] It is often found amongst coastal heath communities.[2]
