Timothy Andrew Hammer


I am a botanist specialising in systematics, biogeography, phylogenetics and taxonomy, with a particular interest in the diversity and evolution of Australian plants. I am currently studying the evolution, systematics and taxonomy of Ptilotus (commonly 'mulla mulla') and other aervoid genera in the amaranth family (Amaranthaceae).
