Alisma gramineum is a small aquatic plant in the water-plantain family. It has several common names including narrowleaf water-plantain, ribbonleaf water-plantain or ribbon-leaved water-plantain,[2] and grass-leaved water-plantain. It grows in mud or submerged in shallow fresh or brackish water in marshy areas.[3]
Description
The leaves and tiny purple-tinted white flowers may be submersed or not. When the flowers grow underwater they are cleistogamous, meaning they stay closed and self-pollinate. When the flowers grow above water they open. The leaves above the surface are stiff and wide, but submerged leaves are ribbon-like. The fruit is a ring of dry nutlets. Reproduction is by seed or from division of the corm.[4]
Distribution
Alisma gramineum is widespread across temperate and subarctic portions of Asia and Europe and North Africa from France and Libya to China and Yakutsk. It is reported from much of Canada from British Columbia to Quebec, as well as most of the western United States plus New York, Vermont and Virginia.[5][6][7][8] This is an endangered and protected species in the United Kingdom.[9]
