Ptilotus aristatus, commonly known as pink pussy-tail,[2] is a species of flowering plant in the family Amaranthaceae and is endemic to Central Australia.

Ptilotus aristatus is an annual or perennial herb that typically grows up to 40 cm (16 in) high.

There are usually two fertile stamens and three staminodes, the ovary is hairy and the style is 1.6–4.0 mm (0.063–0.157 in) long.

[3] Ptilotus aristatus was first formally described in 1961 by Gerhard Benl in the journal Mitteilungen der Botanischen Staatssammlung Munchen from specimens collected near Charlotte Waters in 1939.

aristatus occurs in the Northern Territory near the South Australian border and as far south as the Evelyn Downs station, where it grows in open vegetation on gibber plains and slopes, sometimes on nearby floodouts.
