Eudicots are a clade of angiosperms. They are named for the observation of two cotyledons on the embryo during development, although they share various other differences to their sister clade, the monocots.
In addition to possessing two cotyledons, eudicots possess netted veins, a simple ring structure arrangement of vascular bundles in their stem and shoot cells, a taproot system, and develop flowering organs in patterns of fours or fives.
Eudicots include both herbaceous and woody plants, such as roses, beans, and oak trees.
