Original diagnosis/description
As for the genus with the following additions: Seed envelope elliptical to ovate in outline with a pointed apical protrusion and a slightly concave base. Lateral wings narrow, of almost the same width from base to apex. Surface of seed envelope rugose with irregular transversely oriented ridges. Cells of outer epidermis of the seed envelope longitudinally aligned; narrowly elongate over the midrib, shorter laterally with small circular thickenings along the cell walls.
Etymology
From the ribbed surface of the seed envelope.
