Abstract

Two new species of Leptolobium from Brazil are described and illustrated. Leptolobium araguaiense, restricted to northern Brazil, is similar to L. panamense, but differs in raceme length, ovary pubescence, flower and bract length, hilum shape, habit, geographical distribution, and preferential habitat. Leptolobium multijugum, from midwestern Brazil, is perhaps most closely related to L. glaziovianum, but it has more numerous leaflets and smaller bracts and bracteoles than any other species in the genus.
