In plant taxonomy,
commelinids (originally
commelinoids) (plural, not capitalised) is a name used by the
APG III 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 has informally named within the monocots. The remaining monocots are a
paraphyletic unit.
