Medicago littoralis

Medicago littoralis is an annual plant species of the genus Medicago. Its native range encompasses the Mediterranean Basin, from Macaronesia to the Caucasus; it has been introduced elsewhere. It is useful as a forage for livestock. As a leguminous plant, it is capable of adding nitrogen to soils, through its symbiotic relationship with the bacterium Sinorhizobium meliloti, which enables nitrogen fixation. Common names include shore medick, water medick, coastal medick, and strand medick.
