  1. Valves lanceolate
  2. Apices subrostrate, rounded
  3. Axial area wide
  4. Raphe distinctly lateral
  5. Stria density higher near apices

Cymbopleura edlundii has lanceolate valves with rounded, subrostrate apices. The axial and central areas are very wide, 1/2 to 1/3 the width of the valve. The raphe is distinctly lateral, becoming weakly reverse-lateral at the proximal and distal ends. Striae number 9-13 in 10 µm at the center and 14-16 in 10 µm near the apices.
