Seed elliptical, tapering rapidly toward a blunt to slightly round and asymmetrical apex and rounded at the base; central part elliptical and irregularly spotted, surrounded by a thin margin with a straight median line corresponding to the trace left by the raphe from the apex to the center of the seed. Cells small (~30 μm wide), polygonal, and irregularly arranged.
The specific epithet ellipticum refers to the elliptical shape of the seed.
