I am not aware of any convincingly proteaceous leaves from the Paleogene anywhere else in the Antarctic area, or from Africa, where Proteaceae pollen has been reported from the latest Cretaceous to Paleocene Arnot Pipe of South Africa (Scholtz, 1985).
On current understanding, the pre-Quaternary Banksia-like fossils comprise a very interesting group of species that includes at least stem taxa of both Banksia and Musgraveinae and also a group of species that is only doubtfully proteaceous.
Hill & Christophel must also be considered only doubtfully proteaceous (see Carpenter & Jordan, 1997).
Comparative resprouter percentages of proteaceous genera in the South African fynbos appear lower, which may be an indication that the Australian environment is a more fire-prone environment than are the Mediterranean-climate areas of southern Africa.
Seed production, pollinator attractants and breeding systems in relation to fire response: Are there reproductive syndromes among co-occurring proteaceous shrubs?
