Description
Hakea ilicifolia is an open multi-stemmed shrub or tree typically growing to a height of 1 to 3 metres (3.3 to 9.8 ft). The flowers are in a branching corymb with the foliage thickest at the apex. The branchlets are covered with rusty to woolly white soft, matted hairs. The leaves are stiff, flat, elliptic, 1.5–5 cm (0.59–1.97 in) long, 5–20 mm (0.20–0.79 in) wide, tapering or wedge-shaped at the apex and coarsely toothed. The inflorescence consists of about 16 sweetly scented flowers borne in the leaf axils on outer branchlets, each flower 3–3.5 mm (0.12–0.14 in) long, yellow or cream on a pedicel 3.5–6.5 mm (0.14–0.26 in) long. Flowering occurs from August to October and the fruit is oval shaped, 2–2.2 cm (0.79–0.87 in) long, 1.5–1.6 cm (0.59–0.63 in) wide, warty with two curving horns 3.5–4.5 mm (0.14–0.18 in) long.[2][3][4]
Taxonomy and naming
Hakea ilicifolia was first formally described in 1810 by Robert Brown and the description was published in Transactions of the Linnean Society of London.[5][6] It was named from the genus Ilex - holly and the Latin folium - leaf, referring to the holly-shaped leaves.[3]
Distribution and habitat
Holly-leaved hakea is endemic to a few isolated areas in the Wheatbelt, Great Southern and Goldfields-Esperance regions of Western Australia. It has a scattered distribution between Denmark in the south and west, Dumbleyung in the north and Esperance in the east where it is found on breakaway slopes and near creeks growing in sandy, loamy or clay soils over sandstone or laterite and a part of heathland or low Eucalypt woodland communities.[2]
Conservation status
Hakea ilicifolia is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[2]
