Description

Goodenia xanthosperma is a prostrate herb that typically grows to a height of 1–15 cm (0.39–5.91 in) with stems up to 80 cm (31 in) long. The leaves at the base of the plant are elliptic to egg-shaped, 30–60 mm (1.2–2.4 in) long and 13–30 mm (0.51–1.18 in) wide, with toothed or lobed edges. The flowers are arranged in racemes up to 800 mm (31 in) long on a peduncle up to 50 mm (2.0 in) long with leaf-like bracts and linear bracteoles up to 10–30 mm (0.39–1.18 in) long, each flower on a pedicel 2–25 mm (0.079–0.984 in) long. The corolla is yellow with purplish markings, about 15 mm (0.59 in) long, the lower lobes 5–7 mm (0.20–0.28 in) long with wings about 2 mm (0.079 in) wide. Flowering mainly occurs from May to October.[3][2]
