Ptilotus fasciculatus is a prostrate perennial herb with several hairy stems. The leaves on the stems are linear, long and wide. There are bracts long bracteoles long with a prominent midrib. The flowers are pink or magenta and borne in oval, hemispherical or spherical spikes, the outer tepals long, the inner tepals long. The style is long and fixed to the side of the ovary.
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. The specific epithet (fasciculatus) means 'clustered', referring to the leaves.
This species of Ptilotus grows in the Avon Wheatbelt, Geraldton Sandplains and Mallee bioregions of south-western Western Australia.
Ptilotus falcatus is listed as "Priority Four" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions, meaning that it is known from only one or a few locations where it is potentially at risk.
