Description
editGoodenia blackiana is a prostrate to ascending perennial herb that typically grows to a height of 200 mm (7.9 in), with stems up to 200 mm (7.9 in) long. The leaves are mostly at the base of the plant, egg-shaped to lance-shaped with the narrower end towards the base, 20–60 mm (0.79–2.36 in) long and 5–15 mm (0.20–0.59 in) wide, with cottony, woolly hairs on the lower surface. The flowers are arranged in racemes up to 50 mm (2.0 in) long on a peduncle 30–50 mm (1.2–2.0 in) long, or are solitary in leaf axils. Each flower is on a pedicel 30–50 mm (1.2–2.0 in) long with a linear bracteoles 5–12 mm (0.20–0.47 in) long at the base. The sepals are narrow oblong to egg-shaped, 4–5 mm (0.16–0.20 in) long, the petals yellow, 13–14 mm (0.51–0.55 in) long. The lower lobes of the corolla are 5–6 mm (0.20–0.24 in) long with wings about 2 mm (0.079 in) wide. Flowering mainly occurs from September to January and the fruit is a more or less cylindrical capsule about 10 mm (0.39 in) long.[2][3][4]
