Ptilotus extenuatus is a species of flowering plant in the family Amaranthaceae and is endemic to eastern Australia. It is an erect perennial plant with a woody rootstock, linear to egg-shaped or lance-shaped leaves, and spikes of about 20 crowded flowers. The species is extinct in New South Wales and "critically endangered" in Queensland.
Ptilotus extenuatus is an erect perennial plant with a woody rootstock with stems up to 30 cm (12 in) high that later lie close to the ground. The stems are covered with woolly hairs at first but later become glabrous. The leaves are linear to egg-shaped or lance-shaped, up to 12 mm (0.47 in) long, 3.5 mm (0.14 in) wide and petiolate, about 10–20 mm (0.39–0.79 in) apart. The flowers are borne in spikes up to 120 mm (4.7 in) long with up to 20 crowded flowers, each with three fertile stamens and a club-shaped ovary.[2][3][4]
Taxonomy
Ptilotus extenuatus was first formally described in 1981 by Gerhard Benl in the journal Telopea from specimens collected by Charles Fraser in 1818.[4][5]
