Other Australian states: Qld Vic. Tas.
A polymorphic species variable in leaf shape and size, petiole and pedicel length and degree of pubescence, particularly of ovary and pod. The key to subspecies is useful in some districts of N.S.W. where typical forms of subsp. formosum and subsp. parviflorum are found. In coastal districts, however, subspecies are linked by numerous and various intermediates which cannot be satisfactorily placed in either.

| ||Key to the subspecies|| |
|1||Leaflets usually ovate, length less than twice the breadth, base cordate; ovary hairy on sutures and on valves; pods hairy on sutures and retaining some pubescence on valves||subsp. formosum|
|Leaflets usually narrow-ovate, length more than twice the breadth, base not cordate; ovary glabrous or sparsely hairy on sutures only; pod ± glabrous||subsp. parviflorum|
