 divisions meeting side by side, as in Protea. 



61. Pericarpium, the Seed-vessel, formed of the en-

 ripe, and then, by one means or other, to promote 

 their dispersion. When dry, it often bursts elas-

 animals, who thus convey its contents to a di-

 The partitions originate either from the margins 

 or centre of each valve, or from the central
