Description
Goodenia arenicola is a stolon- or rhizome-forming herb covered with soft hairs. The leaves are mostly clustered at the ends of short stems and lance-shaped with the narrower end towards the base, 40–100 mm long and 8–14 mm wide, sometimes with teeth on the edges. The flowers are arranged singly in leaf axils on a peduncle 30–40 mm long, with linear bracteoles 4–6 mm long. The sepals are linear, 5–6 mm long, the petals yellow and 15–17 mm long. The lower lobes of the corolla are 7–8 mm long with wings about 2.5 mm wide.
