In plant taxonomy, the name commelinids (plural, not capitalised) is used by the APG II system for a clade within the monocots, which in its turn is a clade within the angiosperms. The commelinids are the only clade that the APG II has named within the monocots, the remaining monocots are a paraphyletic unit, occasionally referred to as the "base monocots". A modern system of plant taxonomy, the APG II system of plant classification was published in 2003 by the Angiosperm Phylogeny Group, APG, in Angiosperm Phylogeny Group (2003). ... A clade is group of organisms which share a common ancestor and which includes all decendents of that ancestor. ... Orders Base Monocots: Acorus Alismatales Asparagales Dioscoreales Liliales Pandanales Family Petrosaviaceae Commelinids: Arecales Commelinales Poales Zingiberales Family Dasypogonaceae Monocotyledons or monocots are a group of flowering plants usually ranked as a class and once called the Monocotyledoneae. ... Classes Magnoliopsida - Dicots Liliopsida - Monocots The flowering plants (also angiosperms or Magnoliophyta) are one of the major groups of modern plants, comprising those that produce seeds in specialized reproductive organs called flowers, where the ovulary or carpel is enclosed. ...

The commelinids of APG II (2003) contain basically the same plants as the commelinoids of the earlier APG system (1998).
The name "Commelinid" is preferred, as use of "Commelinoid" may cause confusion with the Commelinoideae, a subfamily of the Commelinaceae.
A monophyletic group of monocotyledonous angiosperms that are united by DNA sequence data as well as the general chemical apomorphy of cell-wall bound, UV-fluorescent ferulates (e.g., ferulic, coumaric, dicoumaric acids).
The Commelinids include the Arecaceae (palm family), Zingiberales (bananas, gingers), Commelinales (defined here as consisting of 4 families), Poales, sensu lato, and an assemblage of other groups of currently uncertain affinities.
