Burkartia Explained

Burkartia is a monotypic genus of flowering plants in the family Asteraceae,^[1] containing the single species Burkartia lanigera.^[2] It is endemic to southern Argentina (Provinces of Chubut, Rio Negro, Santa Cruz).^[3]

This species was formerly in genus Perezia, but it was separated because it has woolly trichomes in the leaf axils, a character not seen in any other Perezia.^[4] The genus Burkartia was erected for it in 1976.^[5] Molecular phylogenetic analyses in 2009 supported its separation from Perezia.^[4]
