It was defined by Russian [[botanist]] [[Nikolai Tzvelev]] in 1990. It was identified before (and takes precedence over) ''Bracteantha'' which was described the following year.<ref name=AP173>{{Cite journal|author=Wilson, Paul G.|year=2002|title=''Xerochrysum'' the correct name for the genus ''Bracteantha''|journal=Australian Plants|volume=21|issue=173|page=398}}</ref> A 2002 molecular study of the tribe [[Gnaphalieae]] found the genus is likely [[polyphyletic]], with ''X. bracteatum'' and ''X. viscosum'' removed from each other.<ref>{{cite journal|last=Randall J.
