Abstract
Three new Australian diploid species in Glycine Willd. are described. Two of these (Glycine gracei B.E.Pfeil & Craven and Glycine montis-douglas B.E.Pfeil & Craven) are endemic to the Northern Territory whereas the third (Glycine syndetika B.E.Pfeil & Craven) is endemic to Queensland. G. montis-douglas is only known from one locality. The genetic affinities of G. gracei and G. syndetika are with other A genome species. The species G. syndetika is the closest relative of a diploid parent of the T2 allotetraploid race of the G. tomentella s.l. Hayata species complex, as well as of allotetraploid G. pescadrensis Hayata, which is here formally reinstated from synonymy. Images are included of the leaflet venation for several species discussed in the paper. Thus, the treatment incorporates evidence from morphology, cytology, DNA sequences and crossing experiments. A key to the subgenera and to the species within Glycine subgenus Glycine is provided, which includes all 25 described Australian taxa.
