Fleabane

Last updated April 01, 2019

Fleabane is a common name for some flowering plants in the family Asteraceae.

The flowering plants, also known as angiosperms, Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 64 orders, 416 families, approximately 13,164 known genera and c. 369,000 known species. Like gymnosperms, angiosperms are seed-producing plants. However, they are distinguished from gymnosperms by characteristics including flowers, endosperm within the seeds, and the production of fruits that contain the seeds. Etymologically, angiosperm means a plant that produces seeds within an enclosure; in other words, a fruiting plant. The term comes from the Greek words angeion and sperma ("seed").

Family is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy; it is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as being the "walnut family".

Asteraceae or Compositae is a very large and widespread family of flowering plants (Angiospermae).

Most are in the subfamily Asteroideae:

Conyza (butterweeds or horseweeds: Astereae)
Erigeron (Astereae)
Inula ("yellowheads": Inuleae)
Pluchea (camphorweeds: Inuleae)
Pulicaria (Inuleae)
Vernonia (ironweeds: Vernonieae)

Conyza is a genus of flowering plants in the sunflower family.

Astereae is a tribe of plants in the family Asteraceae that includes annuals, biennials, perennials, subshrubs, shrubs, and trees. Plants within the tribe are present nearly worldwide divided into 170 genera and more than 2,800 species, making it the second-largest tribe in the family behind Senecioneae. They are found primarily in temperate regions of the world.

Erigeron is a large genus of plants in the daisy family. It is sometimes confused with other closely related genera, Aster and the true daisy Bellis. The genus has a cosmopolitan distribution in dry, mountainous areas and grassland, with the highest diversity in North America.

Aster is a genus of perennial flowering plants in the family Asteraceae. Its circumscription has been narrowed, and it now encompasses around 180 species, all but one of which are restricted to Eurasia; many species formerly in Aster are now in other genera of the tribe Astereae. Aster amellus is the type species of the genus and the family Asteraceae.

The Heliantheae are the third-largest tribe in the sunflower family (Asteraceae). With some 190 genera and nearly 2500 recognized species, only the tribes Senecioneae and Astereae are larger. The name is derived from the genus Helianthus, which is Greek for sun flower. Most genera and species are found in North America and South America, particularly in Mexico. A few genera are pantropical.

Asteroideae is a subfamily of the plant family Asteraceae. It contains about 70% of the species of the family. It is made of several tribes, including Astereae, Calenduleae, Eupatorieae, Gnaphalieae, Heliantheae, Senecioneae and Tageteae. Asteroideae contains plants found all over the world, many of which are shrubby. There are about 1,135 genera and 17,200 species within this subfamily; the largest genera by number of species are Helichrysum (500-600) and Artemisia (550). Asteroideae is said to have begun approximately 46-36.5 million years ago.

Xylothamia, the desert goldenrods, is a genus of flowering plants in the daisy family, Asteraceae. Until 2003, it was held to contain nine species of shrubs native to deserts of Mexico and the southwestern United States. However, it seems to contain at least two groups. Four species are related to Gundlachia and may be moved to that genus. The relationships of the other five species is not quite as clear. All nine species do belong in the subtribe Solidagininae.

Helianthodae is a supertribe in the family Asteraceae, the aster family, containing the tribes Anthroismeae, Coreopsideae, Eupatorieae, Helenieae, Heliantheae, Inuleae, and Tageteae. This supertribe was discovered in 2004 after studying the DNA of plants in the family Asteraceae. The authors used a broad definition of Heliantheae including Bahieae, Chaenactideae, Madieae, Millerieae, Perityleae, and Polymnieae.
