		+	\|Taxon details=''Liliopsida'' is considered the scientific name for monocots, but monocots may be called differently based on different taxonomic classification systems. Based on chloroplast DNA sequences, the divergence date between monocots and dicots is estimated to be ~200 million years, with a 40 million years uncertainty. There are ~50000-60000 species of monocots, with the largest family being ''Orchidaceae'' (orchids) consisting of ~20000 species. The true grasses (''Poaceae'') are the most economically important family, with 70% of the crops being cultivated belonging to this family.
