Perennial herbs with appressed hairs; hairs multicellular with terminal cell papillate. Leaves mostly basal, rosetted, villous in axils. Inflorescences head-like, consisting of several shortly pedunculate cymes, subtended by a long scape, surrounded by an involucre of bracts. Flowers sessile, erect, actinomorphic, bisexual, subtended by 4 membranous hyaline bracteoles; sepals 5, connate, subulate, plumose; petals 5, connate in lower half; stamens 5, opposite sepals, attached to petals; anthers connate, forming a tube, 2-celled, opening by longitudinal slits; ovary superior, 1-celled; ovule 1, attached basally on septum or ridge; style simple, entire with hollow indusium enclosing the more or less bifid tip. Fruit a nut enclosed in persistent calyx; seed without endosperm; testa membranous; embryo straight.
A monotypic genus, endemic to Australia, occurring in all States.
Brunonia has been placed in its own family, but the presence of the stylar indusium in Brunonia and other Goodeniaceae, which is unknown elsewhere in the flowering plants, clearly places Brunonia with Goodeniaceae.
