Grevillea tetragonoloba (Proteaceae: Grevilleoideae) recircumscribed, with notes on its typification and a new segregate species, Grevillea nivea, described
OLDE, PETER M. AND MARRIOTT, NEIL R.
Grevillea nivea P.M.Olde & N.R.Marriott is the third species that we have segregated and described from Grevillea tetragonoloba Meisner sensu McGillivray. The type citation of Grevillea tetragonoloba is discussed and modified. Recognition of Grevillea nivea as distinct from Grevillea tetragonoloba requires a modified circumscription for the latter species, and a full, updated description is provided here. A key is provided enabling distinction from closely related species.
