A review of the Glycine clandestina species complex (Fabaceae: Phaseolae) reveals two new species

Abstract

Digitate-leaved specimens of the genus Glycine from across southern Australia that have been determined as G. clandestina J.C.Wendl. encompass a wide range of morphological variation. Re-evaluation of this material has resulted in the conclusion that three species should be recognised. The original concept of G. clandestina (digitate-leaved plants with long, c. nine-seeded pods) can be applied only to plants from Queensland, New South Wales, Victoria and Tasmania. Two new species, G. peratosa B.E.Pfeil & Tindale and G. rubiginosa Tindale & B.E.Pfeil, are described from Western Australia and South Australia, respectively. Variation in G. clandestina s.s. is discussed in relation to contact zones with three other closely related species.
