INDIAN OCEAN DISTRIBUTION: Australia, Djibouti, India, Madagascar.

Note: When Linnaeus (1753) is used as the starting point for all cyanophycean nomenclature, as in this catalogue, Oscillatoria laetevirens (P. Crouan & H. Crouan) Gomont must be considered a later homonym of O. laetevirens Hofman-Bang (1818: 23, footnote; type locality: Fyn, Denmark). We retain it, however, because if later starting points were to be abandoned officially, it would be a likely candidate for conservation. Drouet (1968: 111, 116), after examining the holotype of this species (in PC), assigned it to Schizothrix arenaria (Berkeley) Gomont.
