bur medick

Medicago minima (L.) Bartal. is a member of the Fabaceae family and is commonly referred to as bur medick. It is native to the Mediterranean basin but has been introduced and naturalized in many parts of the world, including the United States, Canada, and various regions in Europe, Asia, and South America. The plant is known for its ability to form a symbiotic relationship with the bacterium Sinorhizobium meliloti, which enables nitrogen fixation. It is recognized by several common names, including little bur-clover, little medick, small medick, and woolly bur medick. The species was first described in 1776.
