alismatid monocots
{{short description|Grade of flowering plant orders within Lilianae}}
Alismatid monocots (alismatids, basal monocots) is an informal name for a group of early branching (hence basal) monocots, consisting of two orders, the Acorales and Alismatales. The name has also been used to refer to the Alismatales alone. Monocots are frequently treated as three informal groupings based on their branching from ancestral monocots and shared characteristics: alismatid monocots, lilioid monocots (the five other non-commelinid monocots) and commelinid monocots. Research at the Royal Botanical Gardens, Kew is organised into two teams I: Alismatids and Lilioids and II: Commelinids.{{sfn|ps=none|RBG|2010}} A similar approach is taken by Judd in his Plant systematics.{{sfn|ps=none|Judd et al.|2007}}

Subdivision
{{main|List of alismatid families}}
Of the two orders, the Acorales is monotypic, consisting of a single family, the Acoraceae, which in turn has a single genus, Acorus with two species. By contrast, the Alismatales is a much larger grouping, with about 13 families, 165 genera and about 4,500 species.{{sfn|POWO|2019}}
