Marsh iris or acorus-like iris

Family: Crucifers. Name: translated from Latin Iris pseudacorus means "pseudo-acorus iris" (acorus - acorus), but among the people it has become known as the marsh iris. The latter is related to its ecology.

In the wild it, as a rule, grows in river floodplains, along the banks of water bodies (excluding, of course, bodies of seawater) that occur along its distribution. By its nature, being hydrochorous, i.e. a plant whose seeds are dispersed by water, it cleverly uses this trait to colonize new places for its habitation. Apparently, the dispersal of its seeds is also aided by waterfowl (but this requires experimental confirmation).

Seeds of the marsh iris, when they get into water, do not sink for a long time. The reasons for their high buoyancy lie in the non-wettability of their coat and the presence of air-filled cavities between the coat and the endosperm of the seed. Marsh iris is the only species in the genus Iris that not only is not harmed by human economic activity, but successfully uses it to expand its range. Therefore the marsh iris can be called a hemerophile.
