    The plasticity of morphological features used for morphospecies identification was studied under varied experimental conditions in eight planktonic Anabaena strains. Significant effects of the growth conditions, mostly P concentration, on vegetative cell dimensions were observed in seven strains. Significant effect of an environmental factor (P) on akinete morphology was found in only one strain. Experimentally assessed temperature and light growth optima were specific for each strain and were not consistent with the taxonomic affiliation. Morphologies of the strains studied were compared with the field morphologies of 61 Anabaena populations of eight morphospecies. The range of morphological variability of single strains under the experimental conditions spanned the total variability of the populations of relevant morphospecies observed in the field. Delimitations of the morphospecies were discussed in the light of partial 16S rRNA gene sequences of the studied strains.
