'''''Emblingia''''' is a monospecific plant genus containing the species '''''Emblingia calceoliflora''''', a herbaceous prostrate subshrub endemic to [Western Australia](/source/Western_Australia). It has no close relatives, and is now generally placed alone in family '''Emblingiaceae'''.
==Description==
It is a [perennial](/source/Perennial_plant), [herb](/source/herb)aceous prostrate [subshrub](/source/subshrub), with simple [petiolate](/source/Petiole_(botany)) leaves with "cartilaginous" (hard and tough, resembling cartilage) margins. The irregular, solitary flowers are white, cream, yellow, green or, pink, and occur from August to November. It has a non-fleshy fruit.[{{cite web |author1=Watson, L. |author2=M. J.

==Taxonomy==
The genus and species were first published in 1861 by [Ferdinand von Mueller](/source/Ferdinand_von_Mueller) in ''[Fragmenta Phytographiae Australiae](/source/Fragmenta_Phytographiae_Australiae)'', based on specimens collected in the [Murchison](/source/Murchison_(Western_Australia)) region by [Pemberton Walcott](/source/Pemberton_Walcott) and [Augustus Frederick Oldfield](/source/Augustus_Frederick_Oldfield).[{{APNI | name = Emblingia | id = 57437}}][{{APNI | name = Emblingia calceoliflora | id = 57456}}]
Placement of the genus within a family has previously been considered a difficult problem; it has at various times been placed in [Capparaceae](/source/Capparaceae), [Sapindaceae](/source/Sapindaceae), [Goodeniaceae](/source/Goodeniaceae) and, in the [Cronquist system](/source/Cronquist_system), [Polygalaceae](/source/Polygalaceae).[{{cite journal |author1=Chandler, Gregory T. |author2=Randall J.

==Distribution and habitat==
It is [endemic](/source/endemism) to [Western Australia](/source/Western_Australia), occurring in grey, yellow or red sand, on undulating sandplains of the west coast. It is most common in the [Geraldton Sandplains](/source/Geraldton_Sandplains) and [Carnarvon](/source/Carnarvon_(biogeographic_region)) [biogeographic](/source/biogeography) regions, but also occurs on the north western edge of the [Avon Wheatbelt](/source/Avon_Wheatbelt).
