Description

Xanthosia ciliata is a low, spreading shrub that typically grows to a height of 5–25 cm (2.0–9.8 in), its leaves linear to wedge-shaped. The inflorescence is arranged in leaf axils or on the ends of branches and is usually a small, compound umbel with four short rays. Each partial umbel is subtended by a leaf-like, softly-hairy involucral bract less than 2 mm (0.079 in) long. The sepals are tapering heart-shaped and the petals are yellowish-green to cream-coloured or white. Flowering occurs from October to December or January.[2][3]

Taxonomy and naming

Xanthosia ciliata was first formally described in 1848 by William Jackson Hooker in Icones Plantarum from specimens collected by James Drummond near the Swan River.[4][5] The specific epithet (ciliata) means "fringed with fine hairs".[6]

Distribution and habitat

Xanthosia ciliata grows in lateritic soils, sand or clay in the Avon Wheatbelt, Esperance Plains, Geraldton Sandplains, Jarrah Forest and Swan Coastal Plain bioregions of south-western Western Australia and is listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.[3]
