Peter Olde, OAM, is a world leader in grevilleas. He discusses the effects of various species concepts over time on the genus Grevillea and the significance of results of a recent molecular study which found Hakea deeply nested in Grevillea. Other important discoveries flowing from that study include the origin and age of the earliest evolved species, the surprising position of Grevillea endlicheriana at the base of the resultant phylogenetic tree. If time permits, He shows some new species discovered since publication of the Grevillea Book and the Flora of Australia treatments.
