Botany. 308 are seen in Omithopus, Hedysarum (fig. 556), Entada, Coronilla, and the Gum-arabic plant (Acacia arahica), in -which each seed is con- tained in a separate division, the partitions being formed by the folding in of the sides of the pericarp, and distinct separations taking place at these partitions by what has been termed solubility. The name schizocarp has been also applied to such fruits. In Cathartocarpus Fistula transverse partitions occur without exhibit- ing evident separations of the parts externally. Some look upon these pods as formed by pinnate leaves folded, and the divisions as indicating the points where the different pairs of pinnae are united. Dehiscence may also be effected by partial openiags in the pericarp, called pores, which are situated either at the apex,' base, or side. In the Poppy (fig. 444, p. 249) the opening takes place by numerous pores under the peltate processes bearing the stigmas. In Campanulas there are irregular openings towards the middle or base (fig. 557 t), which pierce the pericarp. In Progsmouth or Snapdragon (fig. 558) the pericarp gives way at certain fixed points, forming two or three orifices, one of which corresponds to the upper carpel, and the other to the lower. These orifices have a ragged appearance at the margins, which has given rise to the name rupturing, as applied to this mode of dehiscence. Oahpology.—Much has been done of late in the study of car- pology (xa^mi, fruit, and Xoyog, discourse), or the formation of the fruit; but much still remaius to be done ere the terminology of this department is complete. Many classifications of fruits have been given, but they are confessedly imperfect, and unfortunately much confusion has arisen in consequence of the same names having been applied to different kinds of fruit. In many cases, therefore, it is necessary to give a de
