Actinodium

Actinodium cunninghamii is a small, compact shrub that typically grows to a height of up to 30 cm (12 in) with leaves about 4 mm (0.16 in) long and 1–2 mm (0.039–0.079 in) wide. The flowers are borne in pinkish-brown, daisy-like heads 20–30 mm (0.79–1.18 in) in diameter. The heads are made up of tiny, bell-shaped flowers surrounded by sterile, strap-like ray flowers.^[4][5]

A related, but as yet undescribed species presently given the name Actinodium sp. 'Fitzgerald River' and also commonly known as Albany daisy, is a sparsely-branched shrub up to 1 m (3 ft 3 in) high with leaves 5–6 mm (0.20–0.24 in) long, the heads pink and white and 40–50 mm (1.6–2.0 in) wide. This species is more common than A. cunninghamii.^[4][6]

The genus Actinodium was first formally described in 1836 by Johannes Conrad Schauer in the journal Linnaea, Ein Journal für die Botanik in ihrem ganzen Umfange^[7][8] and Schauer later described Actinodium cunninghamii in John Lindley's A Natural System of Botany from specimens collected by Allan Cunningham.^[9][10] The genus name is derived from Greek and means "like the spokes of a wheel".^[6][11]

Actinodium cunninghamii grows in moist, sandy soil in forest and kwongan and is uncommon in nature. Both species of Actinodium usually grow in winter-wet depressions in near-coastal areas near Albany in the south-west of Western Australia.^[4][5][12]

Actinodium sp. 'Fitzgerald River' (sometimes as A. cunninghamii) has been grown in gardens but is a short-lived plant requiring good drainage and a sheltered position. It can be propagated from cuttings.^[6][13]

An image of A. cunninghamii was engraved for an Australian Stamp in 1985.^[3]
