Hakea recurva, commonly known as jarnockmert, is a shrub or tree of the genus Hakea native to an area in the Mid West, northern Wheatbelt and the Goldfields-Esperance regions of Western Australia.

Description

Hakea recurva is a tall non-lignotuberous shrub or small tree typically grows to a height of 1 to 6 metres (3 to 20 ft). Multi-stemmed branchlets are appressed with fine silky hairs and quickly becoming glabrescent. The fragrant inflorescence may have 20-40 large cream-yellow flowers in clusters in the leaf axils from June to October. Rigid terete leaves may be straight or recurved ending with a sharp point. Fruit have a smooth surface, obliquely egg-shaped 1.7–2.3 cm (0.7–0.9 in) long ending in broad short beak.

Taxonomy and naming

Hakea recurva was first formally described in 1856 by Carl Meisner and the description was published in Prodromus Systematis Naturalis Regni Vegetabilis.

Distribution and habitat

Hakea recurva grows in open scrub or mulga on granitic loam, sand, sandy-clay, gravel and laterite. Occurs in area bounded by the Murchison River, Laverton and Israelite Bay.

There are two subspecies:

  • Hakea recurva subsp. arida The leaves are generally 4 cm (1.6 in) long and 1.2–1.6 mm (0.047–0.063 in) wide. The overlapping flower bracts 2–3.5 mm (0.079–0.138 in) long, smooth, reddish coloured with a light brown rounded rim. The pedicels 4.5–8 mm (0.18–0.31 in) long and the gland 0.2 mm (0.0079 in) high.
  • Hakea recurva subsp. recurva The leaves are 5–12 cm (2.0–4.7 in) long and 2–3.2 mm (0.079–0.126 in) wide. The over-lapping flower bracts 4–7.5 mm (0.16–0.30 in) long and pale coloured. The pedicels 8–13 mm (0.31–0.51 in) long and the gland 0.8–1 mm (0.031–0.039 in) high.
