Anotations

Scope note:

Genus containing around 3 species of coarse, perennial grasses around one meter (3 feet) in height and native to sandy coasts of temperate Europe, North America, and northern Africa. The utility of these species in stabilizing beaches and forming sand dunes has resulted in the grasses being planted in many beach areas outside of their normal range.
