Various methods of classification have been suggested. 
Corbett (Farmers’ Bulletin 289, pp. 7-8) has proposed 
the following arrangement, which is satisfactory for all 
practical purposes : “For convenience in reference and 
for discussion, beans may be divided into two gen- 
eral groups — ‘field’ and ‘garden’ beans — which are by no 
means distinctly separate either in appearance or in char- 
acteristics. Each of these groups can again be divided 
into bush and pole beans. Bush beans of the field type 
are recognized, for commercial purposes, under three 
well-marked types, known as kidney, marrow and pea 
beans, each of which may be subdivided into two groups, 
colored and white. The garden beans, like the field 
beans, may be divided into bush and pole types ; these 
again into kidneys and limas, the term ‘kidney’ in this 
case including all of the common garden beans whether 
of one type or another, and this group may again be 
divided into wax and green pod. The same subdivision 
may also be provided under pole beans, as is suggested 
in the following classification
