Description[]

Westringia angustifolia is a small shrub, 1–3 m (3 ft 3 in – 9 ft 10 in) high with rigid, spreading branches. The leaves are arranged mostly in whorls of three, about 1.5–3.5 mm (0.059–0.138 in) long, on upright, slender stems about 1–2 mm (0.039–0.079 in) long, slightly bent backwards and a sharp tip at the apex. The lower surface has soft, silky hairs, the upper surface sometimes covered in small, coarse hairs. The flowers are borne in leaf axils on a pedicel, they may be white to pale lilac, with yellow, crimson or purple dots on the lower petals of the throat. Flowering occurs from October to December and most likely pollinated by insects, the fruit is a nutlet with furrowed veins on the surface.[2]
