It has dense, woolly, rusty star-shaped hairs on its stems, lance-shaped leaves densely covered with white and rust-coloured hairs on the lower surface, and white flowers arranged singly or in groups of up to nine in leaf axils or on the ends of branchlets, the back of the petals densely covered with woolly, white hairs.
Description
Asterolasia elegans is an erect, spindly shrub that typically grows to a height of 1–3 m (3 ft 3 in – 9 ft 10 in) with its stems densely covered with woolly, rusty-red, star-shaped hairs. The leaves are lance-shaped to elliptical, 40–130 mm (1.6–5.1 in) long and 9–25 mm (0.35–0.98 in) wide on a petiole 5–15 mm (0.20–0.59 in) long. The leaves are covered with white and rusty-red star-shaped hairs, densely so on the lower surface. The flowers are arranged singly or in umbels of up to nine in leaf axils or on the ends of branchlets, each flower on a pedicel 4–18 mm (0.16–0.71 in) long. The petals are white, elliptical, 8–14 mm (0.31–0.55 in) long, densely covered with white, star-shaped hairs on the back and there are ten stamens.
