Identification notes

The seeds are uniformly ovalOval:
Broadly elliptic.
and symmetrical on the edge view (planar). The furrow between the radicleRadicle:
The rudimentary root of the embryo, developing into the primary root after emergence from the seed coat.
and cotyledonary lobe is approximately parallel to the axis of the seed. The uniformity of the seed is because they are borne in a one-seeded podPod:
A dehiscent fruit produced by leguminous plants (beans, peas). Also known as a legume.
. Occasionally, two seeds are formed in the podPod:
A dehiscent fruit produced by leguminous plants (beans, peas). Also known as a legume.
giving each seed a flat side where they were appressedAppressed:
