Description: Trees, shrubs or herbs, sometimes climbing or twining.

Leaves simple or compound (mostly pinnate or palmate) with 1-many leaflets, rarely absent; stipules usually present.

Inflorescences various; each flower on a pedicel subtended by a lower bract and with often 2 similar bracteoles just below the calyx or attached on the calyx tube. Flowers strongly zygomorphic. Calyx mostly unequally toothed, often 2-lipped. Corolla papilionaceous, petals unequal; upper petal (the standard) usually largest and borne externally to the adjacent lateral petals (wings), lower petals innermost and mostly fused (the keel) and enfolding the stamens and gynoecium. Stamens 10, free or more often monadelphous with the filaments fused to form a closed or open sheath around the gynoecium, or the uppermost filament often ± free so that the stamens are diadelphous; anthers 2-locular, dehiscing by longitudinal slits, all uniform or sometimes dimorphic and alternating in size.

Fruit commonly a pod or sometimes a lomentum; seeds usually arillate, though often inconspicuous.

Distribution and occurrence: World: c. 500 gen., 12 000 spp., widespread, chiefly trop. to temp. regions. Aust.: c. 140 gen., 1100 spp., all States.

The seeds and pods of many of the herbaceous species are eaten by humans as food; these are especially valued for their high protein content. Some, especially species of Trifolium and Medicago, are cultivated and used for feeding to livestock or ploughed in as a fertilizer. A number of species are used for timber, while many species are widely grown as ornamentals.

This subfamily is often treated as the family Fabaceae s.str. or Papilionaceae.

Bituminaria, Centrosema, Phaseolus and Spartium are included in the key to genera but as species of these genera are cultivated as ornamentals or food plants and they are not known to be fully naturalized in N.S.W., they are not described in the text.
