   Sammanfattning : Phylogeny and morphology were examined for the cyanobionts from the water fern Azolla and the cyanobacterial genus Nostoc originating from symbioses with different host plants (genera Gunnera, Cycas, Dioon, Encephalarthos, Macrozamia, and Anthoceros), the lichen genus Pannaria, and free-living Nostoc isolates from different habitats. Nostoc isolates of Pannaria formed a closely related group, but, in general, no monophyletic nature was attributed to the genus Nostoc, in contrast to the cyanobionts from Azolla which were contained in a unique monophyletic group.
