Abstract
An unusual type of akinete formation was observed in cultures ofAnabaena azollae which were not reported in any other cyanobacterium earlier. These akinetes were spherical comparatively larger than the normal ones and covered with a thick inner and thin outer envelopes. It represented transformed vegetative cells which faced temporary growth difficulties in non symbiotic conditions. The germination of the akinete started with an enlargement followed by the division of the cell contents into numerous fragments. Later the each divided cytoplast underwent 3 to 4 divisions and developed into a group of interwoven trichomes.
