Tapetal cells in the anthers of Anthemis tinctoria, Erigeron annus and E. canadensis were uninucleate in the premeiotic stage of the PMC's. Ta-petum differentiation with inhibited cytokinesis took place during the period of meiotic divisions. In E. canadensis both mitoses were normal, wheareas in A. tinctoria and E. canadensis after both first and second mitotic divisions as a result of numerous disturbances polyploid nuclei were formed
