Basionym: Anabaena spiroides Klebahn (1895: 25) View in CoL

Filaments solitary, planktonic; trichomes regularly screw-like coiled, coils 20–60 μm in diameter, constricted at the cross walls, not attenuated towards the ends; often with a broad, colourless mucilage. Vegetative cells spherical, compressed at the poles, dark blue-green in colour, (4.0–) 7.0–9.0 μm long × 6.0–8.5 μm broad, with aerotopes; apical cells undifferentiated. Heterocytes spherical, 7.0–10.0 μm in diameter. Akinetes intercalary, solitary or in series, oval to cylindrical with rounded ends, remote from the heterocytes, (11–) 15.0–21.0 μm long × 9.5–15.0 μm broad.
