| Motility | |
| Specialized structures | Many species of this genus are extreme examples of multi-cellular complexity in the cyanobacteria. Main axes with numerous branches may reach thicknesses of 1 mm Pore channels (synapses of microplasmodesmata) occur between all cells derived by divisions Branches, although initially simpler than the main axis, eventually become as complex. Tips of branches may be uniseriate for a considerable distance |
