Ίρις η ψευδάκορος (Iris pseudacorus), είναι είδος ελοχαρές, γνωστό σε όλη την Ελλάδα ως «νεκρόκρινο».
Iris pseudacorus (yellow flag, yellow iris, water flag, lever) is a species in the genus Iris, of the family Iridaceae. It is native to Europe, western Asia and northwest Africa. Its specific epithet, meaning "false acorus," refers to the similarity of its leaves to those of Acorus calamus, as they have a prominently veined mid-rib and sword-like shape.
t is an herbaceous flowering perennial plant, growing to 100–150 centimetres (39–59 in) (or a rare 2 metres (6 ft 7 in)) tall, with erect leaves up to 90 centimetres (35 in) long and 3 centimetres (1.2 in) broad. The flowers are bright yellow, 7–10 centimetres (2.8–3.9 in) across, with the typical iris form. The fruit is a dry capsule 4–7 centimetres (1.6–2.8 in) long, containing numerous pale brown seeds. I. pseudacorus grows best in very wet conditions, and is often common in wetlands, where it tolerates submersion, low pH, and anoxic soils. The plant spreads quickly, by both rhizome and water-dispersed seed. It fills a similar niche to that of Typha and often grows with it, though usually in shallower water. While it is primarily an aquatic plant, the rhizomes can survive prolonged dry conditions.
Large I. pseudacorus stands in western Scotland form a very important feeding and breeding habitat for the endangered corn crake.
I. pseudacorus is one of two iris species native to the United Kingdom, the other being Iris foetidissima (stinking iris).
In some regions it has escaped from cultivation to establish itself as an invasive aquatic plant which can create dense, monotypic stands, outcompeting other plants in the ecosystem. Where it is invasive, it is tough to remove on a large scale. Even ploughing the rhizomes is often ineffective. It has been banned in some areas but is still widely sold in others for use in gardens.
The rhizome has historically been used as an herbal remedy, most often as an emetic.[citation needed] When applied to the skin or inhaled, the tannin-rich juices can be acrid and irritating.
This plant has been used as a form of water treatment since it has the ability to take up heavy metals through its roots.
