Daviesia pedunculata is a spreading or sprawling to erect shrub that typically grows to a height of . Its phyllodes are erect, usually egg-shaped to elliptic, mostly long, high and usually sharply-pointed. The flowers are arranged in leaf axils on a raceme of three to eight flowers, the raceme on a peduncle long, the rachis up to long, each flower on a pedicel long. The sepals are long, the upper two lobes joined for most of their length and the lower three long. The standard petal is broadly egg-shaped with a notched centre, long and wide, yellow with a maroon base around a yellow centre. The wings are about long and maroon, the keel long and maroon. Flowering occurs from July to December and the fruit is a flattened, triangular pod long.[1]
Daviesia pedunculata was first formally described in 1839 by John Lindley from an unpublished description by George Bentham. Lindley's description was published in A Sketch of the Vegetation of the Swan River Colony.[2] [3] The specific epithet (pedunculata) means "pedunculate".[4]
