Xylothamia
Xylothamia
Genus of flowering plants
Xylothamia, the desert goldenrods,[1] is a genus of flowering plants in the family Asteraceae.[2][3][4][5] Until 2003, it was held to contain nine species of shrubs native to deserts of Mexico and the southwestern United States.[6] However, it seems to contain at least two groups. Four species are related to Gundlachia and may be moved to that genus. Plants of the World Online (part of the Royal Botanic Gardens, Kew) class it as a synonym of Gundlachia.[7] The relationships of the other five species is not quite as clear. All nine species do belong in the subtribe Solidagininae.[6]
