Calytrix harvestiana

Calytrix harvestiana is a glabrous shrub that typically grows to a height of up to 75 cm (30 in). Its leaves are spreading to erect, linear, elliptic or egg-shaped, 2.0–4.5 mm (0.079–0.177 in) long and 0.7–1.25 mm (0.028–0.049 in) wide on a petiole 0.25–0.75 mm (0.0098–0.0295 in) long. There are no stipules. The flowers are borne on a peduncle 3.4–4.0 mm (0.13–0.16 in) long with broadly elliptical to more or less round, lobes 2.0–2.5 mm (0.079–0.098 in) long. The floral tube has 10 ribs and is 3.5–4.5 mm (0.14–0.18 in) long and surrounds the style. The sepals are fused at the base, elliptic to broadly elliptic, 2.75–3.0 mm (0.108–0.118 in) long and 2.0–2.5 mm (0.079–0.098 in) wide. The petals are purplish mauve to purple or violet and become ochreous to reddish purple near the base, otherwise all yellow, and not changing colour. The petals are elliptic, narrowly elliptic or egg-shaped, 5.5–6.5 mm (0.22–0.26 in) long and 2–3 mm (0.079–0.118 in) wide and there are about 60 to 70 pale yellow stamens in multiple rows. Flowering from September to December and the seed is oval, about 2.5 mm (0.098 in) long and 0.7 mm (0.028 in) wide.

Calytrix harvestiana grows in sandy heath and Casuarina campestris heath in the Kalbarri-Yuna district in the Geraldton Sandplains bioregion of Western Australia.
