[368.] The Legume or true Pod, such as the peapod (Fig. [393]), and the fruit of the Leguminous or Pulse family generally, is one which opens along the dorsal as well as the ventral suture. The two pieces into which it splits are called Valves. A Loment is a legume which is constricted between the seeds, and at length breaks up crosswise into distinct joints, as in Fig. [394].
369. The pods or dehiscent fruits belonging to a compound ovary have several technical names: but they all may be regarded as kinds of
[370.] The Capsule, the dry and dehiscent fruit of any compound pistil. The capsule may discharge its seeds through chinks or pores, as in the Poppy, or burst irregularly in some part, as in Lobelia and the Snapdragon; but commonly it splits open (or is dehiscent) lengthwise into regular pieces, called Valves.
