Description
editGoodenia exigua is a glabrous, stoloniferous perennial that typically grows to a height of 10 cm (3.9 in). The leaves are borne on the stems in irregular whorls of spatula-shaped leaves with a yellowish tip. The leaves are up to 10 mm (0.39 in) long and up to 3 mm (0.12 in) wide. The flowers are borne in cymes or are solitary, with linear bracteoles 1–2 mm (0.039–0.079 in) long at the base. The upper sepal is D-shaped, about 1 mm (0.039 in) long and the petals are about 2 mm (0.079 in) long, glabrous and yellow with short wings. The capsule is more or less round and contains wingless seeds about 1 mm (0.039 in) in diameter.[2]
