Swainsona parviflora is a low-lying perennial plant with a few slender, hairy stems. The leaves are imparipinnate, mostly less than long with 5 to 11 narrowly elliptic to narrowly lance-shaped or oblong leaflets, the side leaflets mostly long and wide with stipules long at the base of the petioles. The flowers are purple, long, arranged in racemes of 3 to 11, long, on a peduncle long. The sepals are joined at the base to form a tube long, with lobes equal to or slightly longer than the tube. The standard petal is long and wide, the wings long and the keel long and deep.[1] [2]
Swainsona parviflora was first formally described in 1864 by George Bentham in his Flora Australiensis from specimens collected near Wide Bay by John Carne Bidwill.[3] [4] The specific epithet (parviflora) means "small-flowered".[5]
This species of swainsona grows in well-watered grassland on the Northern Tablelands, North West Slopes and plains of New South Wales and in south-eastern Queensland.
