Asterolasia rivularis is a small, upright shrub, with narrow leaves and yellow flowers. It has a restricted distribution in New South Wales.
Asterolasia rivularis is a small shrub to 1.5 m (4 ft 11 in) high with young branches covered in brown to grey star-shaped, short matted hairs. The leaves may be narrowly oblong, narrow-oblong to wedge shaped and tapering at the base, 1–2.5 cm (0.39–0.98 in) long, 2–3 mm (0.079–0.118 in) wide. The leaf upper surface has occasional star-shaped hairs, underside brownish star-shaped to short matted hairs, margins slightly rolled under and narrowing to a short petiole. The flowers are either borne from leaf axils or at the end of branches in small clusters of 1-3, yellow petals about 6 mm (0.24 in) long, upper surface with rusty star-shaped to short matted hairs. The pedicels are up to 3 mm (0.12 in) long when in flower. Flowering occurs in early spring. [2] [3]
