Ptilotus fasciculatus is a species of flowering plant in the family Amaranthaceae and is endemic to the south-west of Western Australia. It is a more or less prostrate, perennial herb with several hairy stems, linear stem leaves and spikes of pink or magenta flowers.

Description

Ptilotus fasciculatus is a prostrate perennial herb with several hairy stems. The leaves on the stems are linear, 3–10 mm (0.12–0.39 in) long and 0.5–1 mm (0.020–0.039 in) wide. There are bracts 4.5–4.8 mm (0.18–0.19 in) long bracteoles 4.9–5.7 mm (0.19–0.22 in) long with a prominent midrib. The flowers are pink or magenta and borne in oval, hemispherical or spherical spikes, the outer tepals 13–14.8 mm (0.51–0.58 in) long, the inner tepals 12–14.2 mm (0.47–0.56 in) long. The style is 5.3 mm (0.21 in) long and fixed to the side of the ovary.[2]

Taxonomy

Ptilotus fasciculatus was first formally described in 1912 by William Vincent Fitzgerald in the Journal of Botany, British and Foreign from specimens he collected near Cunderdin in 1907.[3] The specific epithet (fasciculatus) means 'clustered', referring to the leaves.[4]

Distribution

This species of Ptilotus grows in the Avon Wheatbelt, Geraldton Sandplains and Mallee bioregions of south-western Western Australia.[2]
