About Westringia rigida R.Br.
Westringia rigida, commonly called stiff westringia, is a rounded, stiff shrub that reaches 30 to 60 cm (12 to 24 in) in height, and often has tangled branches. Its sessile leaves are mostly produced in whorls of three. The leaves are dark green, linear to slightly wider toward the lower half, reaching up to 10 mm (0.39 in) long and 1–2 mm (0.039–0.079 in) wide. Leaf margins are recurved or revolute, both leaf surfaces are sparsely to densely hairy, and the leaf apex ends in a short point. The green calyx has a densely hairy outer surface; its bracteoles grow up to 1–1.5 mm (0.039–0.059 in) long. The corolla is 6–7 mm (0.24–0.28 in) long, white, and often has a mauve tinge. It has two upper lobes, and three lower lobes marked with small reddish to orange-brown dots. Flowering occurs mostly in spring, and the fruit produced is a wrinkled achene. This species grows on sandy soils in mallee and dry forest habitats, found across Queensland, New South Wales, Western Australia, South Australia and Victoria.
