a pod; a species of seed-vessel which has two valves or external openings including a number of seeds that are fastened along one future only. In this last circumstance the seed-vessel in question differs from that termed by botanists filigera, in which the inclosed seeds are fastened alternately to both the futures or joinings of the pod.

The seed-vessel of all the pea-bloom or butterfly-shaped flowers, the diadipha of Linneus, is of this pod-kind. Such, for instance, is the seed-vessel of the pea, vetch, lupine, and broom.
