Description

Ptilotus humilis is a straggly perennial herb, that typically grows to a height of 40 cm (16 in) and has intertwined branches. Its leaves are lance-shaped, mostly 15–25 mm (0.59–0.98 in) long and 3–4 mm (0.12–0.16 in) wide. The flowers are arranged in cylindrical spikes 25 mm (0.98 in) long and 15 mm (0.59 in) in diameter and whitish grey with a purplish tinge and with hairy, egg-shaped bracts. The perianth segments are 10–12 mm (0.39–0.47 in) long with a purplish tinge. There are five stamens and the ovary is glabrous. ^[2]
