This type opens along bothsutures into two distinct valves; legumes are found in peas, beansand clovers, in fact, the name of our great nitrogen-gathering family ofplants is leguminosae. A compound fruit consisting of several dehisc-ing pods bound together is called a capsule. There are several methodsby which capsules open to let out the seed; when they split alongthe cepta between the pores it is known as septicidal dehiscence, whenopening in this manner the locules composing the fruit remain entireand then themselves dehisce as if they were follicles.

The opening may take place atdifferent parts of the capsule, that is near the top, when it is knownas apical dehiscence, or near the bottom when it is called basal. Indeshiscent Fruits—A dry, one-seeded, indehiscent pericarp is thesimplest form of this type and is called an akene, example, the dande-lion. Winged indehiscent fruits as in the maples and ash are knownas samarus, or key-fruits. We next come to the fleshy fruits in which the seed is liberated by thedecay of the envelops. Botanically a berry is a fleshy pericarp withseeds imbedded in it: the horticulturist, however, calls any small edi-ble fruit a berry: the t
