|Scientific Name:||Alisma plantago-aquatica|
Alisma plantago-aquatica subspecies michaletii Asch. & Graebn.
|Taxonomic Notes:||Although there is some uncertainty regarding the taxonomy of populations close to A. plantago-aquatica in Asia, these do not affect evaluation of the species in Europe.
Plants with the leaves similar to that of A. plantago-aquatica, styles as in A. gramineum and 0.2-0.3 mm long undeveloped anthers are known from Orenburg Region (basin of the Ural and Samara Rivers). Apparently this is the result of hybridization of A. plantago-aquatica × A. gramineum and possibly sterile. These are known as A. ×bjorkqvistii Tzvel. (Tzvelev 2001). This hybridisation is not sufficiently frequent to affect evaluation of the species.
A. plantago-aquatica is reported to hybridise occasionally with A. lanceolatum (A. ×rhicnocarpum Schotsm.) but this is not sufficiently frequent to affect evaluation of the species in Europe.
|Red List Category & Criteria:||Least Concern ver 3.1|
This species is classed as Least Concern as it is widespread with stable populations and does not face any major threats.

This species is widespread and abundant throughout its known range. There is no detailed information available on population size.
|Current Population Trend:||Unknown|
|Habitat and Ecology:||
A. plantago-aquatica is a herbaceous perennial amphibious Helophyte. It occurs mainly in the lowlands and will grow in most mesotrophic to eutrophic wetland types, from the margins of streams and rivers, to lakes, ponds and marshy pools, as well as some artificial habitats such as canals and ricer fields. It is a good colonist and will often form extensive and locally dominant stands in recently excavated pools on basic clays.
|Use and Trade:||
It is widely used as an ornamental plant for outdoor water features in northern Europe. Its root and leaves are used for medicinal purposes as an antibacterial, anticholesterolemic, diuretic, hypoglycaemic, and hypotensive in Viet Nam.
There are no known past, ongoing, or future threats to this species
|Conservation Actions:||There are no conservation measures in place and none are needed.|
