Calytrix purpurea

Calytrix purpurea is a spreading shrub that typically grows to a height of 30–60 cm (12–24 in). Its leaves are linear, 3–10 mm (0.12–0.39 in) long and 0.6–1 mm (0.024–0.039 in) wide on a petiole 0.5–1.0 mm (0.020–0.039 in) long. There are no stipules at the base of the petiole. The flowers are borne on a peduncle 5.5–8.0 mm (0.22–0.31 in) long with elliptic to egg-shaped lobes with the narrower end towards the base, 3–5 mm (0.12–0.20 in) long. The floral tube is narrowly conical, about 5 mm (0.20 in) long and has 10 ribs. The sepals are fused at the base, with egg-shaped, the narrower end towards the base, to oblong lobes 0.5–0.6 mm (0.020–0.024 in) long and 1.25–1.40 mm (0.049–0.055 in) wide. The petals are purple with a yellow base, egg-shaped, 7.5–8.5 mm (0.30–0.33 in) long and 3.0–3.75 mm (0.118–0.148 in) wide, and there are about 45 to 55 yellow stamens in four rows, and that turn deep dirty cream-coloured as they age. Flowering occurs in September and October.

Calytrix purpurea grows on sand plains and sand dunes in coastal heath and in Melaleuca scrub in the Kalbarri district and the Champion Bay district in the Avon Wheatbelt and Geraldton Sandplains bioregions in the south-west of Western Australia.
