Hakea obliqua, commonly known as needles and corks, is a shrub in the family Proteaceae and is endemic to an area in the Wheatbelt, Great Southern and Goldfields-Esperance regions of Western Australia.

Description

Hakea obliqua is an erect, dense shrub typically growing to a height of 0.5 to 3 metres (1.6 to 9.8 ft) and does not form a lignotuber. The branchlets and new growth are rusty coloured. The leaves are needle-shaped, rigid, thick and 1–7 cm (0.39–2.76 in) long, 1.1–2.5 mm (0.043–0.098 in) wide ending in a sharp, erect point. The inflorescence consist of 2-8 white-cream-yellow flowers sometimes with a greenish tinge on a stem 1.3–5 mm (0.051–0.197 in) long. The strongly scented flowers are in clusters in the leaf axils. The pedicels are 3.5–6 mm (0.14–0.24 in) long and densely covered with flattened silky white hairs that extend onto the 4.5–7.5 mm (0.18–0.30 in) long perianth. The pistil is 5.5–10 mm (0.22–0.39 in) long. The large rounded fruit are 2–4.5 cm (0.8–2 in) long and 2–4.5 cm (0.8–2 in) wide. The young fruit are smooth and as they age the surface becomes covered in thick angular cork outgrowths. The fruit taper at the apex with either a curved or straight point 1–6 mm (0.039–0.236 in) long. Flowering occurs from May to October.

Taxonomy and naming

This species was first described by Robert Brown in 1810 and published the description in Transactions of the Linnean Society London. The specific epithet obliqua is derived from the Latin obliquus - "oblique, referring to the nectar gland which is on a slant from the flower axis".

Distribution and habitat

Hakea obliqua is found in southern Western Australia from the Stirling Range to Albany area to Israelite Bay and inland to Pingrup. Grows in heath and scrubland on sand and sandy loam.

Conservation status

Hake obliqua is classified as "not threatened" by the Western Australian Government.
