regards temperature, and as a result it can be grown successfully 

 in the United States only within comparatively narrow limits. In 

 Florida and along the Gulf coast it has, in recent years, become 

 an important forage and green-manuring crop. In those sections 

 where it can be successfully grown it is a worthy competitor of 

 the cowpea and soy bean. 



Cowpeas. The cowpea (Vigna sinensis\ because of its bean- 

 like seed and habits of growth, its economic importance as a 

 forage crop for the production of hay and silage, and its value as 

 a green manure, should be mentioned in connection with the 

 other plants to which it is so closely related both botanically and 

 economically. 



Field and garden beans. For convenience in reference and in 

 discussion, beans may be divided into two general groups, field 

 beans and garden beans, which are by no means distinctly separate 

 either in appearance or in botanical characteristics. Each of these 

 groups may be subdivided into bush beans and pole beans. Field 

 bush beans are recognized, for commercial purposes, under three 

 well-marked types known as kidney, marrow, and pea beans, each 

 of which may again be divided into colored and white varieties. 

 The garden beans of both the bush and the pole type consist of 

 kidney and Lima beans, but practically all the common garden 

 varieties, whether of the bush or the pole type, are known simply 

 as kidney beans. The kidney beans in turn may be divided 

 into wax-podded and green-podded. The following classification 

 may be helpful :
