Goodenia parvisepta is a glabrous, perennial herb with erect or ascending flowering stems up to 40 cm (16 in) long.

Flowering mainly occurs from September to January and the fruit is a more or less spherical capsule containing seeds about 2 mm (0.079 in) in diameter.

[2][3][4] This species was first formally described in 1967 by Roger Charles Carolin who gave it the name Velleia parvisepta in the Proceedings of the Linnean Society of New South Wales.

[4][5] In 2020, Kelly Anne Shepherd and others transferred it to the genus Goodenia as G. parvisepta in Australian Systematic Botany.

[6][7] Goodenia parvisepta grows in damp situations in the Goonoo State Forest in New South Wales.
