Species: [1]
Symphyotrichum is a genus of over 100 species and naturally occurring hybrids of herbaceous annual and perennial plants in the composite family, Asteraceae, most which were formerly treated within the genus Aster. The majority are endemic to North America, but several also occur in the West Indies, Central and South America, as well as one species in eastern Eurasia. Several species have been introduced to Europe as garden specimens, most notably New England aster and New York aster.
Astereae is a tribe of plants in the family Asteraceae that includes annuals, biennials, perennials, subshrubs, shrubs, and trees. They are found primarily in temperate regions of the world. Plants within the tribe are present nearly worldwide divided into over 250 genera and more than 3,100 species, making it the second-largest tribe in the family behind Senecioneae.
Toiyabea is a genus of North American plants in the tribe Astereae within the family Asteraceae. The genus is named for the Toiyabe Mountains in the US state of Nevada.
Xylothamia, the desert goldenrods, is a formerly accepted genus of flowering plants in the family Asteraceae. Until 2003, it was held to contain nine species of shrubs native to the deserts of Mexico and the southwestern United States. As of May 2024, Plants of the World Online divided the nine former species of Xylothamia among Aquilula, Gundlachia, and Medranoa.
Keysseria (island-daisy) is a genus of flowering plants in the family Asteraceae. It includes 11 species, all of which are native to New Guinea with one species also native to northern Borneo.

The species grows primarily in coastal salt marshes, although in the Ozarks it occurs as a non-marine weedy variety.
Erythranthe, the monkey-flowers and musk-flowers, is a diverse plant genus with more than 120 members in the family Phrymaceae. Erythranthe was originally described as a separate genus, then generally regarded as a section within the genus Mimulus, and recently returned to generic rank. Mimulus sect. Diplacus was segregated from Mimulus as a separate genus at the same time. Mimulus remains as a small genus of eastern North America and the Southern Hemisphere. Molecular data show Erythranthe and Diplacus to be distinct evolutionary lines that are distinct from Mimulus as strictly defined, although this nomenclature is controversial.
Diplacus is a genus of flowering plants in the family Phrymaceae, which was traditionally placed in family Scrophulariaceae. It includes 49 species native to the western United States and northwestern Mexico. Most prefer dry and rocky areas.
