Description edit
Goodenia effusa is a spreading annual herb with many stems and that typically grows to a height of 40 cm (16 in). The leaves are needle-shaped, 10–70 mm (0.39–2.76 in) long, 0.3–0.5 mm (0.012–0.020 in) wide and often curved. The flowers are arranged in racemes up to 150 mm (5.9 in) long, each flower on a pedicel 8–35 mm (0.31–1.38 in) long and with leaf-like bracts at the base. The sepals are narrow egg-shaped, 2–4 mm (0.079–0.157 in) long and the corolla is yellow and 12–16 mm (0.47–0.63 in) long. The lower lobes of the corolla are 1.5–3 mm (0.059–0.118 in) long with wings 1–2 mm (0.039–0.079 in) wide. Flowering mainly occurs from March to May and the fruit is more or less spherical, slightly flattened capsule 3–6 mm (0.12–0.24 in) in diameter.[2]
