Jul 11, 2020 · The asterids (Asteridae), with ∼100,000 species, include nearly one quarter of the extant angiosperm species and are thus the largest subgroup in eudicots. The bulk of the species belongs to the former subclass Asteridae and includes many economically important crops ( Magallón and Castillo 2009 ).
Asterids. In the APG IV system (2016) for the classification of flowering plants, the name asterids denotes a clade (a monophyletic group). Asterids is the largest group of flowering plants, with more than 80,000 species, about a third of the total flowering plant species.
In asterid eudicots, including Lamiales, there are several well-supported examples of reversal to actinomorphy from zygomorphy [14,52]. Perhaps the best-documented case is that of Plantago, which has actinomorphic four-merous flowers, but is phylogenetically nested within a clade mostly possessing zygomorphic five-merous flowers.
The asterids are one of the largest subgroups of the flowering plants, with more than 75,000 species. Within the asterids, these species are divided about equally between two large clades (evolutionary lineages), shown in the diagram above.
Apr 1, 1999 · The main group within the eudicots, here referred to as the main cudicot clade, is formed by a basal grade of species-poor lineages, mostly of "lower" Hamamelididae, and a large monophyletic...
The Asteridae is the final large group that we will examine in the Eudicots. This monophyletic group is well supported by molecular data and has many distinct morphological characters as well. Today we will look at two of the basal orders, Cornales (Cornaceae) and Ericales (Ericaceae, Theaceae, Primulaceae, Polemoniaceae), of the Asteridae.
