placentiferous at the middle, and the median nerves of the three carpels, united by 

 their bases and tops, and crowned by the dry floral envelopes, persist after the 

 valves fall away. In the circumsciss capsule 

 (pyxidium, c. circumscissa) , the dehiscence is 

 transverse (Plantain, Pimpernel, fig. 537 ; Purs-

teeth or valves, and leaves an opening between them. In the Primrose, the capsule 

 is five-valved at the top, by the fission of the dorsal nerves of the carpels. In 

 the Pink (fig. 541), both the dorsal nerves and placental sutures split. In Lychnis 

 (fig. 542), the capsule is similarly incompletely ten-valved. In the Poppy (fig. 543), 

 the capsule opens by small tooth-like valves between the septa, below the disk 

 formed by the style and stigmatic rays. In the Harebell (fig. 544), the capsule 

 opens by five small valves at the base of the receptacular tube ; these openings 

 are formed by the lower portions of the septa separating from the central axis, 

 and carrying up with them a portion of the pericarp, in the shape of a little 

 open door. In other species of Campanula the opening occurs at the upper part 

 of the receptacular tube, where the edge of the septum is thickened and forms
