Lasiopetalum rosmarinifolium

Lasiopetalum rosmarinifolium is an erect or spreading shrub that typically grows to a height of 0.3–1 m (1 ft 0 in – 3 ft 3 in), its stems and leaves covered with star-shaped hairs. The leaves are linear, 15–60 mm (0.59–2.36 in) long and 2–4 mm (0.079–0.157 in) wide. The flowers are arranged in small groups, each flower on a pedicel 2.5–3 mm (0.098–0.118 in) long with three hairy bracteoles 2.5–6 mm (0.098–0.236 in) long at the base of the sepals. The sepals are white, 6.5–10 mm (0.26–0.39 in) long, fused for less than half their length, and there are no petals. The anthers are 2.2–2.4 mm (0.087–0.094 in) long on filaments 1.5–2.5 mm (0.059–0.098 in) long. Flowering occurs from June to November.

This lasiopetalum grows in sandy and gravelly soils in the Avon Wheatbelt, Esperance Plains, Hampton and Mallee biogeographic regions of south-western Western Australia.
