Description

Hakea macrorrhyncha is an erect shrub or small tree, single-stemmed or forked close to the ground 1.8–6 m (6–20 ft) high. Branchlets are densely covered with short soft matted hairs and remain until flowering. Needle like leaves are often grooved below 4.5–9 cm (2–4 in) long and 0.9–1.5 mm (0.04–0.06 in) wide. Appearing white initially and densely covered with matted hairs becoming smooth without hairs. An inflorescence of 3−4 flowers appear in leaf axils. The main stalk is rounded 0.5–0.7 mm (0.02–0.03 in) long covered with white woolly hairs. The individual white flower stalks are 4–5.5 mm (0.2–0.2 in) long and moderately covered with soft matted hairs. The short cream-white sepals and petals are 3–3.8 mm (0.1–0.1 in) long moderately to densely covered with white soft short hairs. The style is 6.5–8 mm (0.3–0.3 in) long and recurved. Laterally broad egg-shaped fruit 35–45 mm (1–2 in) long, 21-25 or up to 30 mm wide with a network of wrinkled veins with small blister-like protuberances on a smooth surface, tapering to a long-triangular beak.[2][3] Cream-white flowers appear from August to September.[4]
