portant point is, that while there are many cap- 

 sules in which the dehiscence is so undisguised 



that we can express it 

 accurately by a single

 315. The pod of the 

 mignonette (Fig. 257) 

 is familiar. It is a 

 pouch with a single 

 cavity, and is open at 

 the top. If a pod is 

 examined, the seeds will 

 be found attached to 

 the walls in several 

 more or 

 less definite placentae. We suspect, 

 therefore, that the fruit is really made 

 up of more than one carpel, notwith- 

 standing its apparent simplicity. If, 

 now, we go back to the flower, we 

 find the pistil closed, and as many 

 sessile stigmas as there are to be 

 lobes or angles on the mouth of the 

 pod. The dissepiments are wanting,
