Timothy Andrew Hammer is an Australian botanist and plant taxonomist at the University of Adelaide and State Herbarium of South Australia.[1] He was awarded a PhD from the University of Western Australia in 2019, completing a thesis on the taxonomy and systematics of Ptilotus and related genera in Amaranthaceae.[2][3][4][5] In addition to Ptilotus, he has published taxonomic revisions and new species for the very diverse genus Hibbertia in the family Dilleniaceae,[6] and he has authored the Flora of Australia treatments of Dilleniaceae, including the genera Dillenia, Hibbertia and Tetracera.[7] In 2021, Tim Hammer and Kevin Thiele submitted proposals to amend the International Code of Nomenclature for algae, fungi, and plants to allow the rejection of offensive scientific names.[8][9][10]
