Holly-leaved Mirbelia

Mirbelia dilatata is an erect, bushy, sometimes almost weeping shrub that typically grows to a height of 0.5–3 m (1 ft 8 in – 9 ft 10 in). Its leaves are wedge-shaped, 10–35 mm (0.39–1.38 in) long, with three to seven sharply-pointed lobes 3.2–6.5 mm (0.13–0.26 in) long. The leaves are leathery, the base tapered, sometimes to a short petiole. The flowers are arranged singly in leaf axils or in racemes on the ends of branches, on a short pedicel and are about 15 mm (0.59 in) wide. The sepals are 4–5 mm (0.16–0.20 in) long and joined at the base, the lobes about the same length as each other. The petals are pink, bluish-purple or violet, the standard petal twice as long as the sepals and the wings shorter than the standard. Flowering occurs from September to January and the fruit is an oblong pod about 12 mm (0.47 in) long.

Holly-leaved mirbelia grows in gravelly and sandy soils or laterite in a range of habitats, including forest, woodland and kwongan. It is found in the Avon Wheatbelt, Esperance Plains, Jarrah Forest, Mallee, Swan Coastal Plain and Warren bioregions of south-western Western Australia.
