Xerochrysum (syn. Bracteantha) is a genus of flowering plants native to Australia . It was defined by Russian botanist Nikolai Tzvelev in 1990, preceding (and taking precedence over) Bracteantha which was described the following year.[1][2] A 2002 molecular study of the tribe Gnaphalieae has indicated the genus is probably polyphyletic, with X. bracteatum and X. viscosum quite removed from each other.[3]
