Description
Westringia rigida is a shrub growing 30–60 cm (12–24 in) high, rounded, stiff and often with tangled branches. The sessile leaves mostly borne in whorls of three, dark green, linear to slightly wider on lower half, up to 1–2 mm (0.039–0.079 in) wide, 10 mm (0.39 in) long, margins recurved or revolute, both surfaces sparsely to densely hairy and a short point at the apex. The outer surface of the green calyx is densely hairy, bracteoles up to 1–1.5 mm (0.039–0.059 in) long, corolla 6–7 mm (0.24–0.28 in) long, white, frequently with a mauve tinge, two upper lobes, and three lower lobes with reddish to orange-brown small dots. Flowering occurs mostly in spring and the fruit is a wrinkled achene.[2][3]
