Description

[edit]

Hakea psilorrhyncha is an erect very prickly shrub typically growing to a height of 1 to 4 metres (3.3 to 13.1 ft) with a slender growth habit and does not form a lignotuber. The terete leaves grow alternately on branchlets and are 2–10 cm (0.8–4 in) long and 1.5–2.5 mm (0.059–0.098 in) wide ending with a very sharp point. The branchlets and new leaf growth is a rusty colour. The inflorescence consists of 6-8 sweetly scented brown-yellow clusters of flowers in the leaf axils on a stem 5–5.5 mm (0.20–0.22 in) long. The pedicel is 6–8 mm (0.24–0.31 in) long and thickly covered in cream-white to deep yellow, flattened silky hairs. The perianth 6.5–9 mm (0.26–0.35 in) long and the pistil 10–11 mm (0.39–0.43 in) long. The large ovoid fruit are rough and corky 3–5 cm (1–2 in) long by 1.5–2.5 cm (0.6–1 in) wide ending with a curving short beak. Flowering occurs from September to October.[2][3][4][5]
