Taxonomic notes: Black (1943) confused this and related species which he referred to J. pallidus, J. pauciflorus, J. polyanthemos (sic) and J. vaginatus. Dr L. Johnson's revision of the group (Section Genuini) has not been published but all the species definitely known to occur in S.Aust. are treated here. Other species in this group recognised here are J. amabills, J. aridicola, J. australis, J. continuus, J. effusus, J. flavidus, J. pallidus, J. procerus, J. radula, J. sarophorus, J. subsecundus and J. usitatus. J. polyanthemus is native in Qld and N.S.W.; a specimen of J. vaginatus from S.Aust. (no definite locality) at Kew may not actually be from this State. It occurs in Qld; N.S.W.; Vic.; Tas. and possibly W.Aust.
