Eudicotsoreudicotyledonsare a group offlowering plants.They are one of two majorclades,thenon-magnoliid dicots.Their sister group is theMagnoliids,a much smaller group.[1]
Thedicotsandmonocotsare the flowering plants which took over in the longCretaceousperiod. They largely replaced the earlier types of plants. Of the old forests of theMesozoicera,only theconifersare still common today.
The big groups of eudicots are therosidsandasterids(together 70% of angiosperms).Monocotsmake up most of the rest.[2]
A few examples of eudicots areforget-me-not,cabbage,apple,dandelion,buttercup,mapleandmacadamia.
The tree forms offlowering plantsevolved during theCretaceousperiod. These began to displace theconifersduring theTertiaryera (66 to 2 million years ago). Forests covered much of the globe before the climate cooled.[3]
