In the APG II system (2003) for the classification of flowering plants, the name asterids refers to a clade (a monophyletic group).[1]
Most of the taxa belonging to this clade had been referred to the Asteridae in the Cronquist system (1981) and to the Sympetalae in earlier systems.[citation needed] The name asterids (plural, not necessarily capitalized) is presumably[by whom?] inspired by the earlier botanical name but in itself is intended to be the name of a clade rather than a formal ranked name, in the sense of the ICBN. This clade is one of the two most speciose groups of eudicots, the other being the rosids. It consists of:[1]
- clade asterids :
- clade euasterids I
-
-
- family Boraginaceae
- family Icacinaceae
- family Oncothecaceae
- family Vahliaceae
- order Garryales
- order Solanales
- order Gentianales
- order Lamiales
-
-
- clade euasterids II
-
-
- family Bruniaceae
- family Columelliaceae (+ family Desfontainiaceae)
- family Eremosynaceae
- family Escalloniaceae (+ family Tribelaceae)
- family Paracryphiaceae (+ families Sphenostemonaceae and Quintiniaceae)
- family Polyosmaceae
- order Aquifoliales
- order Apiales
- order Dipsacales
- order Asterales
