'''Eudicots''' and '''Eudicotyledons''' are terms introduced by Doyle & Hotton (1991) to refer to a group of [[flowering plant]]s 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 [[clade]]s of angiosperms, [[monocots]] being the other. The remaining dicots are sometimes referred to as '''[[paleodicot]]s''' but this term has not been widely adopted as it does not refer to a [[monophyletic]] group.
A large number of familiar plants are eudicots. A few are [[forget-me-not]], [[cabbage]], [[apple]], [[dandelion]], [[buttercup]], [[maple]] and [[macadamia]].
Another name for the eudicots is '''tricolpates''', a name which refers to the structure of the [[pollen]]. The group has tricolpate pollen, or forms derived from it. These pollen have three or more [[pore]]s set in furrows called colpi. In contrast, most of the other [[seed plants]] (that is the [[gymnosperms]], the [[monocots]] and the paleodicots) produce monosulcate pollen, with a single pore set in a differently oriented groove called the sulcus. The name "tricolpates" is preferred by some botanists in order to avoid confusion with the [[dicot]]s, a non-monophyletic group (Judd & Olmstead 2004).
The name '''eudicots''' (plural) is used in the [[APG system]], of 1998, and [[APG II system]], of 2003, for classification of [[angiosperms]]. It is applied to a [[clade]], a [[monophyletic]] group, which includes most of the (former) [[dicotyledon]]s.
;Subdivision
Within the "eudicots" or "tricolpates" the main groups are the "'''rosids'''" (core group with the prefix "eu−") and the "'''asterids'''" (core group with the prefix "eu−").
