It is a small, spreading shrub with needle-shaped leaves and clusters of red flowers with 5 petals and 5 stamen bundles.

Description

Calothamnus oldfieldii is a small shrub growing to a height of about 1.5 metres (5 ft). Its leaves are 25–50 millimetres (1–2 in) long and nearly circular in cross section and taper to a pointed end. [3] [4]

The flowers are bright red and arranged in small groups and the stamens are arranged in 5 claw-like bundles. Flowering occurs from July to November and is followed by fruits which are woody capsules about 5 millimetres (0.2 in) long. [3] [4]

Taxonomy and naming

Calothamnus oldfieldii was first formally described in 1862 Ferdinand von Mueller in Fragmenta Phytographiae Australiae from specimens collected near the Murchison River by Augustus Oldfield. [1] [5] The specific epithet (oldfieldii) honours the collector of the type specimens. [5]

Distribution and habitat

Calothamnus oldfieldii occurs in the Carnarvon, Geraldton Sandplains and Yalgoo biogeographic regions [4] where it grows in sandy kwongan. [3] [6]

Conservation

Calothamnus oldfieldii is classified as "not threatened" by the Western Australian government department of parks and wildlife. [4]
