The species are herbaceous plants or small shrubs . The leaves are varied.

The inflorescences are thyrses , grapes or ears . The flowers are hermaphroditic. The cup is free or overgrown. The overgrown crown is spurred in some species, and mostly two-lipped. At the top (adaxial) the corolla tube is deeply split. The upper lip consists of two lobes, the shorter lower lip consists of three lobes. The stamens are free. The ovary is above and usually two-sided. The anatropic ovules are in two rows per compartment or scattered about, rarely individually. Pollination occurs by insects ( entomophilia ).

The fruit is usually a capsule fruit , rarely a small, single-seeded nut fruit or a large, hard, four- seeded stone fruit . The seeds are rich in oily endosperm , flat, and mostly winged.

The basic chromosome number is x = 8.

The range of the species Goodenia armstrongiana , Goodenia purpurascens and Goodenia pumilio extends to New Guinea , that of Goodenia pilosa extends to Indonesia , southern China and the Philippines .
