Austroflourensia
''Austroflourensia'' is a genus of flowering plants in the family Asteraceae. It includes 12 species of shrubs and subshrubs native to South America, ranging from Peru to southern Argentina, typically on arid and semi-arid lands. Most of the species in this genus were previously included in genus ''Flourensia'', which included both North American and South American species. Molecular phylogenetic and morphological studies found that ''Flourensia'' as previously circumscribed was polyphyletic, and in 2023 12 South American species were placed in the new genus ''Austroflourensia''. The species in ''Austroflourensia'' are distinguished from the North American species by its shrubby or subshrubby habit, capitula always radiate and usually arranged in weakly cymose-corymbose capitulescences, 2-3-seriate phyllary, phyllaries, and shortly dentate leaf, dentate disc Corolla (botany), corollas. ''Austroflourensia'' is related to the other four genera in subtribe Enceliinae – ''Encelia' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flourensia
''Flourensia'' is a genus of flowering plants in the family Asteraceae. It contains subshrubs and shrubs, which are commonly known as tarworts. They are found in the southwestern United States, Mexico, and central South America (Bolivia and northern Argentina). The genus name honours French physiologist Jean Pierre Flourens (1794–1867). Phylogenetic studies found that the genus as previously circumscribed was polyphyletic, and in 2023 many of the South American species were placed in the new genus ''Austroflourensia''.Freire SE, Ospina JC, Aagesen L, Espinar LA, Panero JL, Scataglini MA.
