Vegetative cells cylindrical, barrel-shaped or spherical, shorter or longer than wide, pale or bright blue-green or olive-green in colour, without aerotopes, sometimes with granular contents; apical cells may be slightly elongated, conical, conical rounded or spherical. Heterocytes spherical, widely oval or cylindrical, sometimes elongated, usually slightly larger than vegetative cells. Akinetes spherical, oval or cylindrical, solitary or many in series, intercalary, developing paraheterocytically, adjacent to or near the heterocytes. Cells divide crosswise and grow to the original size before the next division; without meristematic zones. Reproduction by trichome fragmentation and by akinete production.</paragraph>
