eudikotil

Eudicotyl, often shortened to eudicot, refers to a major clade of flowering plants. This group, which includes the vast majority of dicotyledonous plants, is characterized by specific botanical features. The term "eudicot" is derived from "eu," meaning "true," and "dicotyledon," indicating that these plants typically have two embryonic leaves or cotyledons. This distinguishes them from other groups of dicots.

Key anatomical and morphological traits define eudicots. Their pollen grains usually possess three pores or furrows, a significant difference from the single furrow found in most other seed plants. Eudicot flowers often display parts in multiples of four or five, though exceptions exist. Their vascular bundles in the stem are arranged in a ring, a pattern that allows for secondary growth and the formation of wood in many species. The roots of eudicots typically exhibit a taproot system.

Eudicots represent a highly diverse and ecologically significant group, encompassing a vast array of familiar plants. This includes many trees, shrubs, herbs, and vines. Examples of prominent eudicot families include the roses (Rosaceae), legumes (Fabaceae), sunflowers (Asteraceae), and oaks (Fagaceae). Their evolutionary success is attributed to a combination of factors, including adaptations related to pollination and seed dispersal.
