Abstract: | This paper deals with a filamentousCyanophycea from aSphagnum bog whose position in the current system is dubious. A characteristic feature, among others, is a certain rhythm of cell division and bipartition of the filaments. As a consequence, only 8-, 16- and 32-celled filaments are present in the population. An occasional disturbance of the rhythm is transitory. In the longitudinal direction the filaments exhibit mirror symmetry in regard to their middle. |
