The eudicots can be divided into two groups: the basal eudicots and the core eudicots. Basal eudicot is an informal name for a paraphyletic group. The core eudicots are a monophyletic group.
Dec 28, 2016 · Core eudicots comprise more than 70% of living angiosperm species and both major clades within the group are well represented in the Late Cretaceous. Late Cretaceous rosids include a rich record of early Fagales (e.g. [ 5 ]) as well as diverse fossils related to other clades [ 1 ].

The name "eudicots" (plural) is used in the APG system, of 1998, and APG II system, of 2003, for classification of angiosperms. It is applied to a clade, a monophyletic group, which includes most of the (former) dicots. Subdivisions. The eudicots can be divided into two groups: the basal eudicots and the core eudicots. [3]
Apr 7, 2022 · The ancestral core-eudicot genome is hypothesized to contain seven chromosomes (Eu1–Eu7) marked with seven different colors. The post-γ ancestral genome consists of three chromosomal ...
Dec 28, 2016 · Eudicots, the most diverse of the three major clades of living angiosperms, are first recognized in the latest Barremian-earliest Aptian. All Early Cretaceous forms appear to be related to species-poor lineages that diverged before the rise of core eudicots, which today comprise more than 70% of angiosperm species.

Within the eudicots there is a large clade called the core eudicots, nearly all members of which show major differences in floral morphology from that of other flowering plants. In particular, the basic construction of the flower is much more stereotyped than in the basal eudicots, monocots, and basal dicots.
The core eudicots are an extremely large, diverse assemblage of flowering plants, with an enormous range of variation in habit, morphology, chemistry, geographic distributions, and other attributes. Based on analyses of morphology, classical systematists did not previously recognize the core eudicot group. Instead, the circumscription of the ...
