40 RANUNCULACE^E [CH. 



In the Hellebores, Caltha (Fig. 3), Peonies, Columbines, 

 Larkspurs, Monkshoods (Fig. 7), &c. we have an aeterio of 

 Follicles : they dehisce by the dorsal suture in Glaucidium, 

 also in Xanthorrhiza whose follicles are 1-seeded. In 

 Nigella the circle of follicular carpels fuse to a septicidal 

 Capsule with inflated dorsal walls in N. damascena (Fig. 

 38). In Hydrastis and Actcea we have a similar fusion,
