Alismatales (alismatids) is an order of flowering plants including about 4500 species. Plants assigned to this order are mostly tropical or aquatic. Some grow in fresh water, some in marine habitats.
Family: Araceae (Arum Family)
Also known as the arum family, members are often colloquially known as aroids. Many plants in this family are thermogenic (heat-producing). Their flowers can reach up to 45 °C even when the surrounding air temperature is much lower. One reason for this unusually high temperature is to attract insects (usually beetles) to pollinate the plant, rewarding the beetles with heat energy.
Family: Alismataceae (Water-plantain Family)
The water-plantains (Alismataceae) are a family of flowering plants, comprising 11 genera and between 85 and 95 species. The family has a cosmopolitan distribution, with the greatest number of species in temperate regions of the Northern Hemisphere. Most of the species are herbaceous aquatic plants growing in marshes and ponds.
