under section ''Rossolis''. In 1996, taxonomist Jan Schlauer argued for the recognition of this taxon at the rank of subgenus, noting that these closely related species share many affinities with subgenus ''

'' but are different enough to warrant subgeneric status. All species in this subgenus are native to northern Australia except for '' D. petiolaris'', which is more widely distributed to as far as
