 showing cauliele (c), plu-

which is thin, transparent and fits snugly. If we 

 cut through the grain, as shown in Fig. 6, we see 

 the germ, consisting 



of a single seed- |5MiJi""ltfi C 



leaf {I) with can 



licle, plumule and a «/- 



large mass of en- 

 dosperm, which in 



Sugar Corn is clear 



and sugary, while 



in ordinary Corn 

 it is hard and yellow on the 

 outside, but flourj^ toward the center. 



in some plants the seed is covered only by the seed 

 coat (the shin of the bean is such 

 a seed -coat), while in others it is 

 covered by the seed- coat plus a 

 part of the seed-case (the seed- 

 case corresponds to the pod of the 

 bean) ; the seed-case may be con- 

 solidated with the seed-coat, 

 as in the. Corn, or be separate 

 from it, as in the Sunflower 

 (Figs. 7 and 8), Peanut (Figs. 

 9 and 10), Walnut (Fig. 24), 

 Peaeh, etc. When the seed- 

 case, or any part of it, remains S. sunflower seed opened, showing
