Triglochin is a genus in the family Juncaginaceae described as a genus by Linnaeus in 1753.[3][4] It is very nearly cosmopolitan in distribution, with species on every continent except Antarctica. North America has four accepted species, two of which can also be found in Europe: Triglochin palustris (marsh arrowgrass) and Triglochin maritima (sea arrowgrass).[5][6] Australia has many more.[1][7]

The most widely used common name for the genus is arrowgrass,[8] although these plants are not really grasses. Many of the common names for species make use of the term "arrowgrass", although there are exceptions: T. procera, for example, is commonly known as water ribbons.

Arrowgrasses are used as food plants by the larvae of some Lepidoptera species including Grey Chi.
