Talk on Tue 2 August — Gondwanan Plants of the Sydney Region

7:30 pm, St Andrews Uniting Church, corner of Vernon Street and Chisholm Street, Turramurra

A large number of plant taxa are shared by New Zealand, South America and Australia but are found nowhere else.

In the 1850s, two pioneering biogeographers (Joseph Hooker and Charles Darwin) spawned different, competing research traditions that remain alive and distinguishable today.

Dr Peter Weston (Honorary Research Associate, Royal Botanic Gardens) will look at Gondwanan plant groups in the Sydney region and consider lines of evidence that allow us to adjudicate between 'Hookerian' and 'Darwinian' biogeographic explanations.
