Tree of Trees

A public display at the Australian National Botanic Gardens illustrating recent research on Acacia phylogeny.

28 August to 14 September, 2009

This is a living display of the evolutionary relationships between Australian wattles (Acacias) called a phylogenetic tree. A tree of trees! The trunk and branches are represented by rope and the plants are clustered according to their evolutionary relationships. Plants close together are closely related - like siblings - while plants that are far apart are more like distant cousins.

These 58 plants belong to a large research project which has a goal to understand the evolutionary relationships of all 1,000 wattle species.
