Description

Beaufortia eriocephala is a compact shrub which grows to a height of 0.5 m (2 ft) and 0.4 m (1 ft) wide. The leaves are arranged in opposite pairs and are linear to narrowly lance-shaped, 5–10 mm (0.2–0.4 in) long and 0.4–0.7 mm (0.02–0.03 in) long. The leaves are hairy but become glabrous with age.[1][2][3]

The flowers are arranged in almost spherical heads on the ends of branches which continue to grow after flowering. The flowers have 5 sepals, 5 petals and 5 bundles of stamens. The stamen bundles contain 3 to 5 stamens each, with the joined part deep red, hairy and 2.5–3.5 mm (0.098–0.14 in) long. The free part of the stamens is red to purple and a further 3–4.5 mm (0.1–0.2 in) long. Flowering occurs from October to December and is followed by fruits which are woody capsules 8.5–10 mm (0.3–0.4 in) long.[1][2][3]

Taxonomy and naming

Melaleuca eriocephala was first formally described in 1905 by the Australian botanist, William Vincent Fitzgerald in Journal of the West Australian Natural History Society.[4] The specific epithet ("eriocephala") is from the Ancient Greek ἔριον (érion) meaning "wool"[5]:864 and κεφαλή (kephalḗ) meaning "head".[5]:399

Distribution and habitat

Beaufortia eriocephala occurs in the Avon Wheatbelt, Geraldton Sandplains, Jarrah Forest and Swan Coastal Plain biogeographic regions.[2] It grows on slopes in sandy soils derived from laterite.[6]

Conservation

Beaufortia eriocephala is classified as "Priority Three" by the Western Australian Government Department of Parks and Wildlife,[2] meaning that it is poorly known and known from only a few locations but is not under imminent threat.[7]
