Description

Valves are linear-clavate with a broadly rounded headpole. In some specimens the headpole may possess an acute tip. The footpole is rounded. Raphe is filiform, straight and does not reach the margin at either pole. The two raphe branches are usually of unequal lengths. Striae are usually short and near the margin, but there may be isolated areolae extending into the broad axial area. The footpole has a higher striae density near the terminus. Stigmata, septa and pseudosepta are lacking.
