Grevillea tesselata Olde (Proteaceae: Grevilleoideae: Hakeinae), a rare new species of uncertain affinity from the Avon Wheatbelt region of south-west Western Australia.
View through CrossRef
Grevillea tesselata Olde is described here as a new species from south-west Western Australia, known only from a small population in a fragmented roadside landscape, and previously recognised under the phrase name Grevillea sp. Trayning (W. Johnston WJ 071). Following the Flora of Australia, the new species keys to the Grevillea Acacioides Group which comprises only three species, G. endlicheriana Meisn., G. acacioides C.A.Gardner ex McGill. and G. gordoniana C.A.Gardner. A binary assessment of 50 morphological characters presented here supports the view that G. acacioides and G. endlicheriana are sister species. A key to the new species is provided and its distribution updated. Grevillea tesselata has a Priority One Conservation Code according to the Western Australian Herbarium.
