Schoenoplectus triqueter
Also called Chair-maker's Rush, Triangular Club-rush, Triangular Bulrush, Three Sided Bulrush
Schoenoplectus triqueter, commonly known as the triangular club-rush, is a species of sedge which lives in temperate Eurasian wetlands, on muddy shores and river margins. It is found across Eurasia, as well as in South Africa, and has been introduced to North America on the west coast. Because of its tolerance of salty habitats, it is considered a halophyte, but plants which were subjected to a high salinity level (10 parts per thousand) in an experiment were noticeably stunted.
S. triqueter inhabits wetlands, shores, and muddy river banks. The species was classified as "Least Concern" by the IUCN in 2013. In some regions, it is classified as endangered, and the species has been extirpated from the Czech Republic. S. triqueter is also known to be in decline in north-central Europe and in the British Isles. However, it grows prolifically enough in China that it is considered a pest in rice paddies.
