Fig. 93. The five carpellary leaves or follicles of Aquilegia, opening by their ventral 

 suture. 



Jig. 94. The carpels of Magnolia glauca with their dorsal sutures open and the 

 seeds suspended from them by curious extensile cords. 



Fig. 95. The legumen or pod of the pea, opening by both sutures at the same time. 

 In the former instances the fruit was univalve, in this case it is bivalve, ep. Epicarp. 

 en. Endocarp. ov. Ovules attached to the placenta pi, by means of the funiculus 

 f. The legume opens by both ventral and dorsal suture. The placenta pi is double, 

 and runs along each edge of the ventral suture. At the apex of the pod are seen 

 the remains of the style and stigma, and at its base the remains of the calyx. 



the dorsal suture, and the several lamina are detached from 

 their midribs. The result of this is, that each of the valves 

 carries on the middle of its internal surface a double lamina or 

 dissepiment, which is composed of a portion of the united 

 laminae of the two different carpels, as in the Martagon lily. 

 (Fig. 97.) This dehiscence is loculicidal (loculus a cell, and 

 ccedo I cut.) 



In septicidal dehiscence each valve is a complete carpel, 

 and generally contains the ovules attached to the placenta. 

 Tn loculicidal dehiscence, however, sometimes the placenta 

 accompany the dissepiments, as in the Pansy. Frequently,
