THE PEANUT— THE UNPREDICTABLE LEGUME 



Figure 10. — Peanut seedling, eleven and one-half days old. The root system is well 

 developed. Four leaves of the main axis are visible and the two cotyledonary 

 lateral branches have begun to expand. All of the shoot organs visible here 

 have expanded from fully formed structures of the embryonic epicotyl shown in 

 figure 1. (after Yarhrough, 76.)
