Spyridium glaucum

Spyridium glaucum is an erect or spreading shrub that typically grows to a height of 0.5–1 m (1 ft 8 in – 3 ft 3 in), its young stems densely hairy, the hairs pressed against the surface. Its leaves are usually egg-shaped with the narrower end towards the base, sometimes oblong to elliptic, 12–16 mm (0.47–0.63 in) long and 5–9 mm (0.20–0.35 in) wide on a petiole 2–4 mm (0.079–0.157 in) long, and with the edges turned down or rolled under. The flowers are borne in heads of 3 to 6, the heads 3–6 mm (0.12–0.24 in) wide and densely covered with rust-coloured hairs. The floral tube is 0.8–1 mm (0.031–0.039 in) long and the sepals 0.7–1.2 mm (0.028–0.047 in) long. Flowering occurs from September to November.[2][3]

Spyridium glaucum was first formally described in 1995 by Barbara Lynette Rye in the Nuytsia from specimens collected by Eleanor Marion Bennett near Ravensthorpe in 1979.[2][4] The specific epithet (glaucum) means "bluish-green or grey", referring to the colour of the leaves.[2]

This spyridium is only known from hills north-east of Ravensthorpe in the Esperance Plains bioregion of south-western Western Australia.[2]
