Description

Goodenia expansa is an annual or short-lived perennial, prostrate herb that spreads up to 1 m (3 ft 3 in) and is covered with white hairs. The leaves are arranged at the base of the plant and are narrow elliptic to lance-shaped with the narrower end towards the base, 50–80 mm (2.0–3.1 in) long and 5–20 mm (0.20–0.79 in) wide with toothed edges, on a petiole 20–40 mm (0.79–1.57 in) long. The flowers are arranged in leafy racemes up to 60 cm (24 in) long on a peduncle 6–30 mm (0.24–1.18 in) long, each flower on a pedicel 6–35 mm (0.24–1.38 in) long.
