Morphological groupings are as defined in ref.1. Section I, unicellular cyanobacteria that reproduce by binary fusion or budding; section II, unicellular cyanobacteria that reproduce by multiple fission or by both multiple fission and binary fission; section III, filamentous, nonheterocystous cyanobacteria that divide in one plane; section IV, filamentous, heterocystous cyanobacteria that divide in only one plane; section V, heterocystous, filamentous cyanobacteria that divide in more than one plane.
