Description

Valves are linear to elliptic-lanceolate, with rostrate apices (in most, but not all, specimens). The axial area is lanceolate, widening into a large central area that reaches the valve margins. The raphe is straight, with proximal ends bent slightly to one side. Striae are radiate near the valve center and slightly convergent near the apices.
