Commersonia borealis

Commersonia borealis is a low growing, spreading shrub that typically grows to 0.3–1.5 m (1 ft 0 in – 4 ft 11 in) high and 0.5–1.5 m (1 ft 8 in – 4 ft 11 in) wide and has scattered star-shaped hairs on its new growth. The leaves are egg-shaped to oblong, 10–40 mm (0.39–1.57 in) long and 7–20 mm (0.28–0.79 in) wide on a petiole 1–5 mm (0.039–0.197 in) long with narrowly lance-shaped stipules up to 6 mm (0.24 in) long at the base. The edges of the leaves have rounded lobes and are rolled under, the lower surface densely covered with white, star-shaped hairs. The flowers are arranged in clusters of 7 to 12 opposite leaf axils and are white to cream-coloured and 6–12 mm (0.24–0.47 in) in diameter, the groups on a hairy peduncle 2–8 mm (0.079–0.315 in) long, each flower on hairy pedicel 2–6 mm (0.079–0.236 in) long. The flowers have five white, petal-like sepals up to 7 mm (0.28 in) long, five egg-shaped, creamy-yellow petals 4–5 mm (0.16–0.20 in) long with a yellowish ligule about the same length as the sepals, and a single white staminode. Flowering occurs from July to November and the fruit is a capsule 5–9 mm (0.20–0.35 in) long and densely-covered with white, star-shaped hairs.

Commersonia borealis grows in limy sand or loam over limestone in near-coastal shrubland, open woodland or heath between Shark Bay and Seabird north of Perth and on Dirk Hartog Island in the Geraldton Sandplains, Swan Coastal Plain and Yalgoo bioregions of south-western Western Australia.
