Psoralea rhizotoma is easily distinguished by its rhizomatous rootstock, decumbent floppy flexuous branching habit, long (30-35 mm) peduncles, shiny greenish purple glabrous calyces, striking reddish purple flowers with standard petal usually flushed violet and with a large white M-shaped nectar guide and a purple flash in the cleft. It is similar to P. glabra in that it coppices, but differs in its multi-stemmed suffrutex habit growing up to 1.5 m tall and ±1 m wide (versus an erect or sub-erect rigid resprouting shrub to 3 m tall); with variable numbers of leaflets on flowering shoots (versus same number of leaflets); inflorescences axillary, lax, distributed along the length of seasonal shoots with variously 1-6 flowers per axil (versus axillary in upper axils of seasonal shoots, congested with 1-3 flowers per axil); flowers reddish purple (versus flowers mauve to blue), standard blade ovate-oblong (versus obovate), and peduncles 30-35 mm long, filiform and flexuous (versus 4-11 mm long, stout and rigid).
