Monocotyledon species found in Montana number at least 615. The Montana Natural Heritage Program has identified a number of monocot species as ''Species of Concern''. Monocotyledons are one of two major groups of flowering plants (or angiosperms) that are traditionally recognized, the other being

there are 59,300 species. The largest family in this group (and in the flowering plants as a whole) by number of species are the orchids (family Orchidaceae), with more than 20,000 species. In agriculture the majority of the biomass produced comes from monocots. The true grasses, family
