Asanthus is a small genus of flowering plants in the family Asteraceae, found only in northern Mexico and the southwestern United States. [1] [2] [3]

Each of the species was originally named as a member of Brickellia , and later transferred when King and Robinson named the genus. [4] Asanthus and Brickellia both have cypsela (achenes) with 10 ribs, but in Asanthus the style is glabrous and narrow at the base whereas in Brickellia the style has a pubescent, enlarged base. Molecular phylogenetic analysis has provided support that the two genera represent phylogenetically distinct lineages and thus should be recognized as distinct. [5]

The genus is named for American botanist Asa Gray, 1810–1888. His name is added to the Greek word "anthos" meaning "flower." [6]

Eupatorieae is a tribe of over 2000 species of plants in the family Asteraceae. Most of the species are native to tropical, subtropical, and warm temperate areas of the Americas, but some are found elsewhere. Well-known members are Stevia rebaudiana, a number of medicinal plants (Eupatorium), and a variety of late summer to autumn blooming garden flowers, including Ageratum (flossflower), Conoclinium (mistflower), and Liatris.

<i>Brickellia</i> Genus of flowering plants

Brickellia is a North American genus of about 100 to 110 species of plants in the family Asteraceae, known commonly as brickellbushes. They are found in Canada, the United States, Mexico, and Central America. Many species are native to the American southwest, especially Texas. Brickellia is among the more basal lineages of the Eupatorieae and should not be assigned to a subtribe pending further research.

Flyriella is a genus of perennial flowering plants in the family Asteraceae, and the species are commonly called brickellbush. They are native to Texas and Mexico.

Brickelliastrum is a North American genus of flowering plants in the tribe Eupatorieae within the family Asteraceae. Brickelliastrum has at times been lumped with Brickellia or Steviopsis, but chromosome number (x=10) and molecular data are in agreement in showing that it is distinct from either of these. Despite having the general appearance of Brickellia, members of Brickelliastrum have cypselae that have only 5-7 ribs (vs. 10), funnel-shaped corollas, and a style with an unenlarged, glabrous base.
