Class is a taxonomic rank fitting between phylum and order.
Monocots, also known as monocotyledons, are one of two major groups of flowering plants (or angiosperms that are traditionally recognized, the other being dicotyledons, or dicots. Monocot seedlings typically have one cotyledon (seed-leaf), in contrast to the two cotyledons typical of dicots. Monocots have been recognized at various taxonomic ranks, and under various names (see below). The APG II system recognises a clade called "monocots" but does not assign it to a taxonomic rank.
