Daviesia pectinata, commonly known as thorny bitter-pea, is a species of flowering plant in the family Fabaceae and is endemic to south-eastern continental Australia. It is a dense, rigid shrub with erect, flattened branchlets, crowded, flattened, triangular phyllodes, and yellow to orange and reddish flowers. Description
Daviesia pectinata is a dense, rigid shrub that typically grows to a height of up to  and has branchlets that are triangular in cross-section. Its phyllodes are vertically flattened, triangular and often crowded,  long,  high and sharply pointed. The flowers are arranged in leaf axils in one or two racemes of three to ten flowers, the racemes on a peduncle  long, the rachis  long, each flower on a pedicel  long. The sepals are  long and joined to form a bell-shaped base, the upper two lobes joined for most of their length and the lower three  long. The standard petal is elliptic with a notched centre,  long and  wide, yellow grading to an orange to dark reddish base and yellow centre. The wings are about  long and orange with a reddish centre, the keel  long and orange-brown. Flowering occurs in September and October and the fruit is a flattened, triangular pod  long.
