Description

Hakea newbeyana is a rigid, spreading, rounded shrub typically growing to a height of 1 to 4 metres (3.3 to 13.1 ft) with ascending smooth grey branches and does not form a lignotuber. The branchlets are densely covered in flattened rusty-coloured, soft hairs. The rigid dark green leaves are needle-shaped, 2.5–7.5 cm (0.98–2.95 in) long, 1–2.2 mm (0.039–0.087 in) wide, straight to slightly curved and ending in a sharp point 1–3 mm (0.039–0.118 in) long. The 6-8 small, sweetly scented creamy-white and yellow flowers appear in clusters in leaf axils on a coarse rough stalk 1–4 mm (0.039–0.157 in) long. The over-lapping flower bracts are 4–4.5 mm (0.16–0.18 in) long. The pedicel 2.5–3.5 mm (0.098–0.138 in) long and smooth. The smooth, yellow perianth is 2–3 mm (0.079–0.118 in) long and the pistil 3.8–4.5 mm (0.15–0.18 in) long. Flowering occurs from September to October. The large, grey, egg-shaped fruit are smooth with darker blister-like pitting on the surface and taper to a small blunt beak.[2][3]
