on the drier uplands back from the coast, but does not do so well in such locali- 
ties. One of its disadvantages is that its prickly burs become entangled in the 
wool of sheep. It has become widely disseminated over the ee and adds 
much to the value of the summer pasturage. To establish a crop of this clover, 
the burs may be scattered dara: in autumn. They will root as soon as the 
winter rains come. They may be harrowed or cultivated inin the early spring. 
Medicago falcata. Yellow lucern; Yellow moon trefoil. 
A close relative of alfalfa, much resembling it, but smaller, and with yellow flowers. 
t grows wild in northern Europe, along yopa and fence corners, and in light 
or sterile soils. It has been cultivated to some extent, but is without value,

An annual or biennial elover, widely grown as a pasture plant in wet meadows and 
on stiff, clayey soils which are too poor to grow alfalfa or clover. On rich, moist 
soil if sometimes makes an enormous growth, but ordinarily its only use is in 
pastures. It is sometimes recommended to be sown mixed with white clover for 
lawns, as it remains green through the driest summers.

An Old World pasture plant, which has become widely introduced in the Eastern 
and Southern States, as far west as Texas. It is very similar to M. denticulata in 
appearance and in its feeding qualities, and is often mistaken for the latter.
