Science definitions for eudicotyledon
[ yōō′dī-kŏt′l-ēd′n ]
An angiosperm having two cotyledons in the seed, leaves with a network of veins radiating from a central main vein, flower parts in multiples of four or five, and a ring of vascular cambium in the stem. In contrast to most monocotyledons, eudicotyledons undergo secondary growth. Eudicotyledons are the largest angiosperm group; they include most cultivated plants and many trees.
