A review of Austrocallerya J.Compton & Schrire and Pongamia Adans. (Leguminosae subfamily Papilionoideae) in Australia, and the description of a new monotypic genus, Ibatiria W.E.Cooper, is presented with the support of fresh, dried, spirit-preserved specimens, molecular phylogenetic analysis of plastid and nuclear data, and illustrations. Three Austrocallerya species are confirmed, described and distinguished for Australia. Two varieties of Pongamia pinnata (L.) Pierre are recognised; P. pinnata var. minor (Benth.) Domin is reinstated and is distinguished from var. pinnata by habitat, leaflet number and width, floral bract length and bracteole length. The new genus, Ibatiria, includes a single species, Ibatiria furfuracea W.E.Cooper, from Queensland’s Wet Tropics Bioregion. A second-step lectotype is designated for Pterocarpus australis Endl., and lectotypes are designated for Wisteria megasperma F.Muell. and Pongamia glabra var. minor Benth.
