Biology:Flourensia

From HandWiki

Flourensia is a genus of flowering plants in the family Asteraceae.[1] It contains subshrubs and shrubs,[2] which are commonly known as tarworts.[3] They are found in the southwestern United States, Mexico, and central South America (Bolivia and northern Argentina).[4] The genus name honours French physiologist Jean Pierre Flourens (1794–1867).[2]

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.[5]
