| Clades | |
In the APG II system (2003) for the classification of flowering plants, the name asterids denotes a clade (a monophyletic group).[1] Common examples include the forget-me-nots, nightshades, potatoes, eggplants, tomatoes, peppers, tobacco, petunias, morning glory, sweet potato, coffee, lavender, lilac, olive, jasmine, honeysuckle, ash tree, teak, snapdragon, sesame, psyllium, garden sage, and a number of table herbs such as mint, basil, and rosemary.
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. The name asterids (not necessarily capitalised) resembles the earlier botanical name but 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
Note: “ + ....” = optional as a segregate of the preceding family.

- family Oncothecaceae
- family Vahliaceae
- family Metteniusaceae
- order Garryales
- order Solanales
- order Gentianales
- order Lamiales
- clade campanulids (similar to euasterids II in APG II)
- order Apiales
- order Aquifoliales
- order Asterales
- order Bruniales
- order Dipsacales
- order Escalloniales
- order Paracryphiales
