NationMaster - Encyclopedia: Eudicots

In the APG-system, the names eudicots or tricolpates are applied to a monophyletic group that includes most of the (former) dicotyledons. The remaining, and more primitive, (former) dicots are sometimes referred to as palaeodicots ("palaeo−" = old) even though this is a paraphyletic group. Scientific classification or biological classification is how biologists group and categorize extinct and living species of organisms. ...

The name "eudicots" is formed by adding the prefix "eu−" (="true") to "dicots". The eudicots have those characters that many older textbooks associate with dicots. Since "dicots" is short for "dicotyledons" it is tempting to jump to the conclusion that "eudicots" is short for "eudicotyledons". However, the name is "eudicots".

The name tricolpates refers to the structure of the pollen. The group has tricolpate pollen, or forms derived from it. These pollen have three or more pores set in furrows called colpi. In contrast, most of the monocots and paleaeodicots (the other flowering plants) and gymnosperms produce monosulcate pollen, with a single pore set in a differently oriented groove called the sulcus.

The name "tricolpates" is preferred under the PhyloCode. A name that can be used under the ICBN is Rosopsida (class, based on Rosa).

Subdivision

Within the "eudicots" or "tricolpates" the main groups are the "rosids" (core group has the prefix "eu−") and the "asterids" (core group has the prefix "eu−"):
