(yew di´ kots) [Gr. eu: true + di: two + kotyledon: a cup-shaped hollow] • Members of the angiosperm class Eudicotyledones, flowering plants in which the embryo produces two cotyledons prior to germination. Leaves of most eudicots have major veins arranged in a branched or reticulate pattern. Eukaryotes (yew car´ ry otes) [Gr. eu: true + karyon: kernel or nucleus] • Organisms whose cells contain their genetic material inside a nucleus. Includes all life other than the viruses, Archaebacteria, and Eubacteria.
Eudicots and Eudicotyledons are terms introduced by Doyle & Hotton (1991) to refer to a group of flowering plants that had been called "tricolpates" or "non-Magnoliid dicots" by previous authors. The term means, literally, "true dicotyledons" as it contains the majority of plants that have been considered dicotyledons and have typical dicotyledonous characters. The term "eudicots" has been widely adopted to refer to one of the two major clades of angiosperms, monocots being the other.
