Bossiaea riparia, commonly known as river leafless bossiaea, is a species of flowering plant in the family Fabaceae and is endemic to south-eastern Australia. It is an erect or low-lying shrub with flattened branches, linear young cladodes, leaves mostly reduced to small scales, and yellow and red flowers. Description
Bossiaea riparia is an erect or low-lying shrub that typically grows to a height of up to , and has flattened winged stems, the cladodes  wide. The leaves are reduced to small scales about  long. The flowers are arranged singly or in small groups in recesses on the side of the cladodes, each flower  long on pedicels  long with five or six bracts up to  long at the base and bracteoles about  long near the middle of the pedicel. The five sepals are  long and joined at the base forming a tube, the upper lobes  long and  wide, the lower lobes shorter and narrower. The standard petal is yellow with a red base and about  long, the wings are yellow or brownish-red and  wide, and the keel is red and about  wide. Flowering occurs from August to December and the fruit is a narrow oblong or elliptic pod  long. Taxonomy
