Scale bar = 10 µm.
Valves clavate, with distinctly rostrate headpole. Distinct transapical costae. Variable size.
Scale bar = 10 µm
Shaped like a +
Very wide at central area and thin near poles
Wide striae
Formerly: Fragilaria leptostauron; Staurosira pinnata
Scale bar = 10 µm
Head pole is broader than the foot pole - typical of this genus.
Scale bar = 10 µm
Headpole is broadly rounded, footpole is narrow, the raphe is lateral, no stigma present, striae are radiate
