Lasiopetalum cardiophyllum, is a species of flowering plant in the family Malvaceae and is endemic to the south-west of Western Australia. It is an erect shrub with egg-shaped to heart-shaped leaves and groups of pinkish flowers.

Description

Lasiopetalum cardiophyllum is an erect shrub with many stems, that typically grows to a height of 20–50 cm (7.9–19.7 in), its young stems covered with star-shaped hairs. The leaves are broadly egg-shaped to heart-shaped or triangular, 10–30 mm (0.39–1.18 in) long and 6–30 mm (0.24–1.18 in) wide on a hairy petiole 3–6 mm (0.12–0.24 in) long. The upper surfaces of the leaves is more or less glabrous and the lower surface is covered with woolly, grey, star-shaped hairs. The flowers are arranged in groups of three to six 30–50 mm (1.2–2.0 in) long, the peduncle 20–30 mm (0.79–1.18 in) long, each flower on a pedicel about 8 mm (0.31 in) long with linear bracts about 2 mm (0.079 in) long at the base and a linear bracteole about 2 mm (0.079 in) long at the base of the sepals. The sepals are pink with a dark red base, about 5 mm (0.20 in) long with five egg-shaped lobes 3.7–7.1 mm (0.15–0.28 in) long and there are no petals. Flowering mostly occurs from August to December.[2][3]
