Gastrolobium formosum is a small, trailing shrub, with red flowers, in the pea family (Fabaceae), which grows up to a metre high, on clays and loam in swamps and along river banks.[1] The inflorescence consists of head of four unstalked flowers which is sheathed by a whorl of large bracts, with the flower petals being obscured by the lower calyx lobes.[3] The standard petal is less than on third the keel petal.[3] It is native to the south-west of Western Australia.[1][5]

It was first described as Jansonia formosa by Richard Kippist in 1847,[2][6] with a more detailed description by Kippist in 1851.[3][7] It was transferred to the genus, Gastrolobium in 2002 by Chandler, Crisp, Cayzer, and Bayer.[3]

The specific epithet, formosum, is a Latin adjective, formosus -a, -um, which describes the plant as "well-formed", "handsome", or "beautiful".[8]
