Anatomical diagram of Medicago flowers.

Medicago is a genus of flowering plants, commonly known as medick or burclover, in the legume family (Fabaceae). It contains at least 87 species and is distributed mainly around the Mediterranean Basin,[2][3] and extending across temperate Eurasia and sub-Saharan Africa.[1] The best-known member of the genus is alfalfa (M. sativa), an important forage crop,[4] and the genus name is based on the Latin name for that plant, medica, from Greek: μηδική (πόα) Median (grass).[5] Most members of the genus are low, creeping herbs, resembling clover, but with burs (hence the common name). However, alfalfa grows to a height of 1 meter, and tree medick (M. arborea) is a shrub. Members of the genus are known to produce bioactive compounds such as medicarpin (a flavonoid) and medicagenic acid (a triterpenoid saponin).[3] Chromosome numbers in Medicago range from 2n = 14 to 48.[6]

The species Medicago truncatula is a model legume[7] due to its relatively small stature, small genome (450–500 Mbp), short generation time (about 3 months), and ability to reproduce both by outcrossing and selfing.

Comprehensive descriptions of the genus are Lesinš and Lesinš 1979[8] and Small and Jomphe 1989.[9] Major collections are SARDI (Australia),[10] USDA-GRIN (United States),[11] ICARDA (Syria),[12] and INRA (France).[13]
