The Antarctic/Australian rift valley: Late cretaceous cradle of nortteastern Australasian relicts?
The montane vegetation of northeastern Australasia represents a modified sample of the late Cretaceous flora that fringed the embryonic Southern Ocean in the southern Australasian/Antarctic region. Beauprea, Knightia, Macadamia, Gevuina and/or Hicksbeachia (Proteasceae), Gunnera (Gunneraceae), Ilex...
