32 THE PEANUT— THE UNPREDICTABLE LEGUME 



Figure 3.— Peanut seedling, five and one-half days old. The epicotyl barely exceeds 

 the cotyledons but hypocotyl and primary root have a total length of 164 mm. 

 Note the distinct collar at the transition region and the belated appearance of 

 lateral roots, (after Yarhrough, 76.)
