Description

Asterolasia muricata is a slender, erect shrub that typically grows to a height of about 1 m (3 ft 3 in). It has leathery leaves 7–15 mm (0.28–0.59 in) long on a short petiole with the edges rolled under. The upper surface of the leaves is covered with rough points but the lower surface is covered with woolly, star-shaped hairs. The flowers are sessile, arranged singly or in groups of two or three in leaf axils and on the ends of branchlets, each flower on a pedicel up to 0.5–8 mm (0.020–0.315 in) long. The petals are yellow, broadly elliptical, about 5 mm (0.20 in) long and covered with woolly, star-shaped hairs on the back. There are ten stamens[3][4]
