Description

Hakea stenocarpa is a small, rounded multi-stemmed shrub typically grows to 0.3 to 1 metre (1 to 3 ft) high and forms a lignotuber. The branchlets are more or less smooth at flowering time. The inflorescence is a single raceme of 14-20 sweetly scented white, creamy-white or yellow flowers in leaf axils in the upper branchlets. The smooth pedicels are cream-white, the perianth cream-white and the pistil 4.4–5 mm (0.17–0.20 in) long. The linear leaves are 6–11 cm (2–4 in) long and 2–7 mm (0.08–0.3 in) wide with a prominent pale yellow longitudinal mid-vein. The leaves generally curl in an upward spiral. Unlike most species of hakea the fruit are long, narrow-ovoid, 2.8–3 cm (1.1–1.2 in) long and 0.6–0.8 cm (0.24–0.31 in) wide, tapering to a pointed beak. The fruit are rough and warty where they attach to the branches.[2][3]

Taxonomy and naming

Hakea stenocarpa was first formally described by Robert Brown in 1830 and published the description in Supplementum primum prodromi florae Novae Hollandiae.[4][5] The specific epithet is derived from the ancient Greek stenos (στενός), "narrow" and karpos (καρπός), "fruit",[6][7] referring to the shape of the fruit.[2]

Distribution and habitat

Narrow-fruited hakea grows in heath, low open shrubland and woodland in deep sand, loam, clay and gravel sometimes over laterite. Requires a well-drained site in sun or partial shade. An ornamental shrub, may be used as a groundcover.[2]

Conservation status

Hakea stenocarpa is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[3]
