Description

Cyanothamnus penicillatus is a spreading shrub that grows to a height of 30 cm (10 in). The leaves are sessile and pinnate with three or five leaflets, each leaflet linear to narrow wedge-shaped and 5–12 mm (0.2–0.5 in) long. The flowers are borne singly in leaf axils on a pedicel 1–2 mm (0.04–0.08 in) long. The four sepals are egg-shaped, 1.5–2 mm (0.059–0.079 in) long and the four petals are white and 2–3.5 mm (0.079–0.14 in) long. The eight stamens are slightly hairy and there is a very short point on the end of the anthers. Flowering occurs mainly from October to November. [2] [3]

Taxonomy and naming

This species was first formally described in 1863 by George Bentham who gave it the name Boronia penicillata in Flora Australiensis from a specimen collected by James Drummond. [4] [5] In a 2013 paper in the journal Taxon , Marco Duretto and others changed the name to Cyanothamnus anemonifolus on the basis of cladistic analysis. [6] The specific epithet (penicillatus) is derived from the Latin word penicillum meaning "little tail", "painter's brush" or "tuft". [7]

Distribution and habitat

This boronia grows in sand and has a disjunct distribution between Toodyay and the Fitzgerald River. [2]

Conservation

Cyanothamnus penicillatus is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife. [3]
