Description

Ptilotus extenuatus is an erect perennial with a woody rootstock, stems to 30 cm high, becoming decumbent, tomentose, glabrous with age.

Leaves are linear to ovate to lanceolate, mucronate, to 12 mm long, to 3.5 mm wide, and are sparsely tomentose.

Inflorescence grow to 12 cm long and are terminal. Bracts are ovate to circular, apex attenuate, hairy at the base and along the midrib. Perianth segments are acute with the very apex truncate, and are 9.5–11 mm long. The outer surface is hairy on the lower two-thirds, apex is glabrous, inner surface is mostly glabrous. Has 3 stamens and 2 staminodes. The ovary is stalked, pubescent, densely so at apex.

Distribution

Ptilotus extenuatus was regarded as a rare species many years ago. Just four widely scattered collections of the species have been made- two in NSW and two in the far south of Queensland. The species is now presumed to be extinct.

Habitat and ecology

  • The habitat of Ptilotus extenuatus is unknown; however one specimen label records the soil as ‘grey silty clay’ while another says ‘light sandy soil’.
