Goodenia exigua is a species of flowering plant in the Goodeniaceae family and is endemic to the south of Western Australia. It is a stoloniferous, perennial plant with whorls of spatula-shaped leaves and yellow flowers.

Description

Goodenia 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.

Taxonomy

Goodenia exigua was first formally described in 1863 by Ferdinand von Mueller in his Fragmenta phytographiae Australiae, from a specimen collected by George Maxwell. The specific epithet (exigua) means "small" or "feeble", referring to the habit of the plant.

Distribution

Goodenia exigua is found in the Avon Wheatbelt, Esperance Plains and Mallee bioregions of southern Western Australia.

Conservation status

This species of goodenia is classified as "Priority Two" by the Government of Western Australia Department of Parks and Wildlife, meaning that it is rare or threatened.
