Pollen evidence for Late Cretaceous differentiation of Proteaceae in southern polar forests
Sclerophyllous Adenanthos and Stirlingia (Proteoideae) are now restricted to the S Australian Mediterranean climatic region: Persoonia (Persoonioideae) ranges into higher rainfall areas of E and N Australia. Grevillea exul-Grevillea robusta and Telopea (Grevilleoideae) and Carnarvonia (Carnarvonioid...

Sclerophyllous Adenanthos and Stirlingia (Proteoideae) are now restricted to the S Australian Mediterranean climatic region: Persoonia (Persoonioideae) ranges into higher rainfall areas of E and N Australia.
