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]
This genus and its species names were formerly included in Bracteantha and before that in Helichrysum.
As of January 2014[update] the authoritative Australian Plant Name Index recognises seven formally named species and five accepted species awaiting formal naming, description and publication:[4]
