Description

Hakea macrocarpa is a tree or shrub that typically grows to a height of 1–6 m (3 ft 3 in – 19 ft 8 in) and has furrowed brownish bark and densely woolly-hairy branchlets. The leaves are narrowly linear, 50–350 mm (2.0–13.8 in) long and 3–15 mm (0.12–0.59 in) wide on a petiole is 1–5 mm (0.039–0.197 in) long. The leaves are straight to curved, and densely covered with woolly hairs pressed against the surface at first, later glabrous. Up to 200 flowers are arranged on a floral rachis mostly 60–200 mm (2.4–7.9 in) long, usually with cream-coloured or white woolly hairs pressed against the surface. The flowers are cream-coloured to greenish-yellow, each flower on a pedicel 4–10 mm (0.16–0.39 in) long, the perianth 7–9 mm (0.28–0.35 in) long with a straight or curved style. Flowering mainly occurs from May to August, and the fruit is a follicle 22–40 mm (0.87–1.57 in) long containing a winged seed 18–37 mm (0.71–1.46 in) long and 9–14 mm (0.35–0.55 in) wide with a wing down over half of one side.^[3][4][5]
