Description
editProstanthera rugosa is an openly-branched shrub that grows to a height of 1–1.5 mm (0.039–0.059 in) with branches that are densely hairy, at least when young and have more or less sessile glands. The leaves are egg-shaped to narrow egg-shaped, hairy on the upper surface, have two or three lobes on each side, 3–9 mm (0.12–0.35 in) long and 2–5 mm (0.079–0.197 in) wide on a petiole 0.5–2 mm (0.020–0.079 in) long. The flowers are arranged in leaf axils near the ends of branches with bracteoles less than 0.5 mm (0.020 in) long at the base. The sepals are 4–5 mm (0.16–0.20 in) long forming a tube 2–3 mm (0.079–0.118 in) long with two lobes, the upper lobe 2–3 mm (0.079–0.118 in) long. The petals are mauve with a white tinge, 10–13 mm (0.39–0.51 in) long. Flowering occurs from September to October.[2]
Taxonomy
editProstanthera rugosa was first formally described in 1834 by George Bentham from an unpublished description by Alan Cunningham, of plants collected "on rugged mountains near the Hunter River". Bentham's description was published in his book Labiatarum Genera et Species.[3][4]
