Cytomixis, representing the migration of chromatic material from one cell to another, was observed in PMC's of Polygonum tomentosum Schrank. Cytomixis was observed at all stages of meiosis, but became less frequent in the later stages of meiosis. Direct nuclear fusion and cytoplasmic connections between cells were noted, so that a series of PMC's were sometimes connected togther.Cytomictic cells were often accompined by other meiotic aberrations such as univalents, laggard and disoriented chromosomes. Levels of pollen stainability are low, indicating a high of male sterility in these populations.
