- The article comprises the second part (Nostocales) of our study of little known planktic and metaphytic cyanoprokaryotes (cyanophytes, cyanobacteria) from ponds, lakes and water reservoirs in East and Southern Africa. The morphology and variation of 17 species was studied, and comments about their ecology and taxonomy are included. Seven new species are defined: Anabaena austro-africana, A. carmichaelii, A. bituri, A. maxima, A. nygaardii, Aphanizomenon capricorni and Cylindrospermopsis helicoidea. In one tropical species, Cylindrospermopsis africana, akinete formation was found and described for the first time. These investigations of cyanoprokaryotic algae from Africa indicate the existence of a specific and unique tropical microflora. Based on our findings we predict that many more taxa will be found in the future.

Tidskriftsartikel (refereegranskat)abstract
- This article is the first part (Chroococcales and Oscillatoriales) of a study of little known planktic and metaphytic cyanoprokaryotes (cyanophytes, cyanobacteria) from ponds, lakes and water reservoirs in southern Africa. Thirty-three species were observed, of which 24 are presented with comments. Ten new species are defined, and one species, originally described as a taxonomic form, is recombined to the specific level. Our results demonstrate the specificity of southern African cyanobacterial microflora.
