THE FRUIT.

Capsule, or pod, is the general name for dry scod-vessols which spUt 

 open at maturity in some regular maimer. It presents many dillereut 

 forms. 



The follicle is the fruit of a simple pistil which splits along its inner 

 suture — that is, the suture formed by the united edges of the leatlet which 

 formed the pistil (Fig. 88). 



The legume splits along both sutures, as we see in the bean and pea 

 (Fig. 89). It is common to a large order of plants, the lerjuminume. 



The true capsule is the product of a compound pistil. It may be one 

 or mauy-cellod, and may discharge its seeds through chinks or pores, as in

the poppy (Fig. 90), or burst irregularly, or, as is most common, open by 

 valves. 



Dehiscence by valves is locullcidal when the pod splits down the back 

 of each cell ; septic idal when the cells first sepai-ate from each other 

 through their partitions and then open along their inner margin. 



The silique is the pod found in the cracifera;. It is divided into two 

 colls by a false partition, and generally opens by two valves from below 

 upward (Fig. i)l). 



The silicle is a short, broad silicj[ue, like that of the shepherd's piu'se.
