Hakea baxteri, commonly known as fan-leaf hakea[2] , is a shrub in the family Proteaceae native to an area in the Great Southern and Wheatbelt regions of Western Australia. A species noted for its foliage due to its fan-shaped leaves.

Description

Hakea baxteri is a non lignotuberous tall upright shrub 1–5 m (3–20 ft) with smooth grey bark. Smaller branches and young leaves have densely matted soft rusty coloured hairs becoming smooth when flowering. The dark green rigid leaves are 4–8 cm (2–3 in) long and 3–9 cm (1–4 in) wide, fan shaped with a toothed upper margin narrowing at the base. The inflorescence consists of 4-8 small strongly scented flowers, light red with a green style. They form in clusters on an obscure stem in the leaf axils or on old wood. The pedicel is 3–4 mm (0.1–0.2 in) long and densely covered with rusty-brown raised hairs continuing onto the 7–9 mm (0.3–0.4 in) long perianth. The large fruit have a roughish surface are globular shaped with a small hooked beak. Hakeas are characterised by their woody fruits, each seed pod containing two winged seeds.[2]
