Alismatid monocots

Alisma plantago-aquatica

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 braching from ancestral monocots and shared characteristics: alismatid monocots, lilioid monocots (the five other non-commelenid monocots) and commelinid monocots. Research at the Royal Botanical Gardens, Kew is organised into two teams I: Alismatids and Lilioids and II: Commelinids.[42] A similar approach is taken by Judd in his Plant systematics.They also organise their monocot research into two teams I: Alismatids and Lilioids, and II: Commelinids.^[1] A similar approach is taken by Judd in his Plant systematics.^[2]
