The flat Lessertia capitata fruit pod is membranous and many-seeded. It is greenish yellow and pale brown-red in haphazard patches, the visible veins here red.
The short, broad pod is straighter on the side where the kidney-shaped seeds are attached (inside), bulging roundly on the opposite, longer side. The pod will open at its tip when ripe.
These pods are glabrous, i.e. hairless, unlike those of L. tomentosa that are densely hairy. The calyx at the back of the pod is dark brown-red, contrasting against its cream pedicel.
The pods of plants belonging to the Fabaceae family are also called legumes, a name borne by the plants themselves as well. The seeds inside are sometimes called pulses (JSTOR; iNaturalist).
