• In 1931 an autohexaploid plant was obtained in the progenies of a triploid intersex (22=2X+1Y1+1Y2+18a Fig. 1) of Rumex Acetosa. The chromosomal formula of this plant is:6n 44=4X+2Y1+2Y2+36a (Fig. 4) X:A=4:6In the heterotypic metaphase of PMC of the tripolid mother plant, the author observed sometimes nuclear plates with unreduced chromosome number (22I=2X+1Y1+1Y2+18a Fig. 2). Restitution nuclei were also often observed (Fig. 3). This plant might have been arisen by the conjugation of unreduced male and female gametes which are derived by the abnormality in the reduction division of the mother plant.The plant was very weak and not yet gave inflorescence.
