Ptilotus aphyllus is a species of flowering plant in the family Amaranthaceae and is endemic to the a small area of inland Western Australia. It is a leafless perennial, except when young, and spikes of purple flowers fading to pink and pale orange.
Description
Ptilotus aphyllus is a shrubby perennial with many slender branches that typically grows up to 1 m (3 ft 3 in) high and 45 cm (18 in) wide. Young plants have egg-shaped to linear leaves 6–13 mm (0.24–0.51 in) long and 1.5–2 mm (0.059–0.079 in) wide, older plants have leafless, rush-like stems. The flowers are borne in spikes of up to 15, 7–16 mm (0.28–0.63 in) wide on a hairy rachis. There are hairy bracts 3.2–4 mm (0.13–0.16 in) long and hairy bracteoles 3.8–5 mm (0.15–0.20 in) long and 2.5–3.3 mm (0.098–0.130 in) long at the base of the flowers. The tepals are purple, fading to pink and pale orange, the outer tepals 6.7–8.2 mm (0.26–0.32 in) long and the inner tepals 6.2–7.6 mm (0.24–0.30 in) long. There are five fetile stamens and the ovary is hairy. Flowering occurs from March to May.
