Cogwheel Clover 



Cogwheel clover is grown to a limited extent in Texas on well-drained 

 clay and clay loam soils. It is used for winter pasture and for soil improve- 

 ment. 



Black Medic 



Black medic grows in North Carolina, Tennessee, Arkansas, and 

 States to the south. It produces best on the heavier soils and tolerates 

 relatively dry winters. It is used both as a conservation and a pasture 

 crop. The plant is distributed naturally in pastures, waste places, and 

 meadows. 



ROUGHPEA 



Roughpea, a reseeding winter annual, is grown in North Carolina, 

 Tennessee, Arkansas, eastern Oklahoma, and States to the south. It is 

 also known as singletary, caley, and wild winter pea in various sections 

 of the cotton -producing area. The plant prefers well-drained limestone 

 soils, but grows well on the average acid soils of the South, and on the 

 heavy soils of Mississippi and Alabama. Used for hay, pasture, and soil 

 improvement, roughpea begins growth in the late winter and early spring 

 and continues to midsummer, when it matures. Grazing should be dis- 

 continued when the plants begin flowering, since roughpea is poisonous to 

 livestock at maturity. 



SESBANIA 



Sesbania is a native legume found in New Mexico, Arizona, and the 

 States bordering the Gulf of Mexico. It makes good growth on river 

 bottom locations in both the Southwest and Midsouth. It prefers rich 

 loam soils. Sesbania is a valuable green manure crop, but it is not 

 sufficiently palatable to be used for forage. 



SWEETC LOVER 



Sweetclovers, which may be either biennials or annuals, are widely 

 grown in Ohio, Indiana, Illinois, Minnesota, Iowa, Missouri, the Dakotas, 

 Nebraska, Kansas, Oklahoma, Texas, eastern Montana, Wyoming, and 

 Colorado, and, to a lesser extent, in Florida, Washington, Oregon, and 

 California. They will grow wherever 17 or more inches of rainfalls 

 annually and the soil is not acid. 



This legume serves principally as a pasture or conservation crop. 

 Nutritionally, it is not equal to alfalfa or red clover for hay. Sweetclover 

 hay must be properly cured or ensiled for storage. The green plants con- 

 tain a substance called "coumarin," which, in improperly cured hay or 

 silage, may decompose into "dicumarol." When spoiled hay or silage 

 is fed to cattle, dicumarol may cause both internal and external bleeding. 



There are two important species of white sweetclover- -biennial yellow 

 and biennial white. Biennial yellow possesses greater tolerance to drought 

 than biennial white and therefore is better adapted to the Great Plains.
