Oregano from Lamiales

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]

APG III

Genetic analysis carried out after APG II maintains that the sister to all other Asterids are the Cornales. A second order that split from the base of the Asterids are the Ericales. The remaining orders cluster into two clades, the Lamiids and the Campanulids. The structure of both of these clades has changed in APG III. The phylogenetic tree presented hereafter has been proposed by the APG III-project.^[2]
