Description

Goodenia cusackiana is an erect herb up to 40 cm (16 in) high, but with a woody stem at the base, and densely covered with silvery hairs. The leaves are narrow elliptic to lance-shaped, 30–50 mm (1.2–2.0 in) long and 3–5 mm (0.12–0.20 in) wide. The flowers are arranged in racemes up to 300 mm (12 in) long with linear to triangular bracts at the base, each flower on a pedicel 1–4 mm (0.039–0.157 in) long. The sepals are lance-shaped, 2–3 mm (0.079–0.118 in) long, the corolla yellow, 8–10 mm (0.31–0.39 in) long. The lower lobes of the corolla are 3–4 mm (0.12–0.16 in) long with wings about 1 mm (0.039 in) wide. Flowering occurs from July to September.[2][3]
