Notes on Leguminosae. II

Abarema sapindoides (Cunn.ex Sweet) Kosterm.is: an illegitimate name.Its correct name is Pithecellobaum priuinosum Cunn.ex Benth.The species of Pithecellobaim that occur in Queensland are enumerated.The number of ovules does not clearly distinguish A tplosia Wight & Arn.from Rhynchosia Lour.The two genera are redefined in terms of presence or absence of a rim-aril and of a septate pod.Nomismia Wight & Arn. is recognised to include species not referrable to the other two genera.The combination Nomismia rhomboidea based on Rhynchosia rhomboidea F. Muell.ex Benth. is made.Mirbelia viminalis (Cunn.ex Benth.)C.A. Gardner is recorded from Queensland.MIMOSOIDEAE PITHECELLOBIUM MART.'In recent years many authors (for example, Beadle et a/, (1972), Beadle (1976) ) have followed Kostermans (1954) in referring Australian species previously referred to Pithecellobitum to Abarema Pittier.While examining these species for the forthcoming '"Handbook to the Flora of South-eastern Queensland"' | found that there were unsolved taxonomic and nomenclatural problems, particularly in Pithecellobium prutnosum.Abarema sapindoides (Cunn.ex Sweet) Kosterm., a name in general use, is based on Acacia sapindoides Cunn.ex Sweet which is a name without description and therefore invalid.The first validly published name for the species seems to be Pithecellobium pruinosum Benth., which has never been correctly transferred to Abarema.In the light of recent taxonomic work such a transfer is not now warranted.
