Length Range: 25- 67 µm
Width Range: 9.5-13.0 µm
Striae in 10 µm: 12-16

Description

Larger valves are lanceolate-clavate, angular in outline, with only slightly protracted headpole and broadly rounded footpole. The axial area is narrow, broadening to form a small circular central area. The raphe is lateral and undulate. The striae are radiate, strongly so at the central portion of the valve. The striae are broad, biseriate, with individual areolae observable with oblique light in the light microscope. Longitudinal lines are distinct and positioned near the axial area. A single, distinct stigma is present in the central area.
