Platylobium obtusangulum

Platylobium obtusangulum, commonly known as common flat-pea, is a low evergreen shrub in the family Fabaceae endemic to south-eastern Australia, growing in the understorey of dry sclerophyll forests, woodlands, and heathlands across Victoria, southern New South Wales, Tasmania, and south-eastern South Australia. The plant typically reaches 30 to 90 centimetres tall and is much branched, with slender, weakly arching, sparsely hairy stems that can root where they touch the ground. Leaves are opposite or sub-opposite, simple, sessile or nearly so, broadly triangular to rhombic with obtuse to slightly mucronate apices, 1 to 4 centimetres long, leathery, glabrous, with prominent reticulate venation, and bear two persistent brown papery stipules at the base. The bright yellow to orange-yellow papilionaceous flowers, about 2 centimetres long, have a standard petal with deep red markings at the base and are borne singly or in pairs on short stalks subtended by leafy bracts; flowering is in spring. The fruit is a flattened, sharply ridged, broadly oblong legume 2 to 3 centimetres long, dark brown when mature.
