The Bean 



247 



These beans are perennial, and the thick roots live over 

 winter if they do not freeze, the plants then coming into 

 bearing early. Sometimes the roots are lifted in autumn 

 and carried over winter in sand in the cellar. Commonly, 

 however, the plants are treated in all ways as annuals, as 

 are other pole 



beans. 



Growers ordi- 

 narily do not dis- 

 tinguish sharply 

 between the mul- 

 tifloras and the 



common garden 

 beans. Aside 

 from the dura- 

 t i n of the 

 plants, differ- 

 ences in germi- 

 nation, unlike 

 flower - clusters, 

 the plants differ 

 also in flowers, as 

 seen in Figs. 138 

 and 139 ; note 

 the size, shapes, and also the calyx-bracts and the bracts 

 at the axils. Figs. 135 and 140 may also be compared. 



Sieva and Lima Beans 

 The limas are beans of high quality. They may be 

 thrown into the following classes: 



1. The sieva or Carolina bean (Phaseolus lunatus), a 



142. Lima bean (X 1/3).
