conspicuous dark spot, or spots, near the center of each leaflet. It 

 is similar to California bur-clover in palatability and growth re- 

 quirements, but is not as common or widely distributed. Black 

 medick (M. lupwlina) differs from the other two important annuals 

 chiefly in that its burs are one-seeded, spineless, and merely curved, 

 rather than twisted or coiled. This species is widely distributed in 

 North America, and extends into higher elevations than the other 

 annual species. It is highly regarded as a forage plant and some- 

 times is called nonesuch, indicative of its superior value.
