''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. 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. ==Species== This genus and its species names were formerly included in ''Bracteantha'' and before that in ''Helichrysum''. the authoritative ''Australian Plant Name Index'' recognises seven formally named species and five accepted species awaiting formal naming, description and publication: * ''Xerochrysum bicolor'' – Tasmania * ''Xerochrysum bracteatum'' , Strawflower or Golden Everlasting – NSW, Vic, Tas, SA, Qld, NT, WA * ''Xerochrysum collierianum'' – Tasmania * ''Xerochrysum palustre'' , Swamp Everlasting, syn.: ''Bracteantha'' sp. aff.
