Some capsules are of one locule, but they may have been compound when young (in the ovary stage) and the partitions may have vanished. Sometimes one or more of the carpels are uniformly crowded out by the exclusive growth of other carpels (Fig. 235). The seeds or parts which are crowded out are said to be aborted. There are several ways in which cap- sules dehisce or open. When they break along the partitions (or septa), the mode is known as septi- cidal dehiscence (Fig. 236); In septicidaldehiscence the fruit separates into parts representing the original carpels. These carpels may still be entire, and they then dehisce individu- ally, usually along the inner edge as if they were follicles. When the compartments split in the middle', between the partitions, the mode is loculicidal dehiscence (Fig. 237). In some cases the dehiscence is at the top, when it is said to be apical (al- though several modes of dehis- cence are here included). When the ivhole top comes off, as in purs- lane and garden portulaca (Fig. 238), the pod is known as a pyxis. In some cases apical dehiscence is by means of a hole or clefts.
