Abstract
In the previous paper, the authors (1960) divided 'the sexual characters in spinach into two categories, "growth and sexual habit ", and announced that some differences in the growth habit make it possible to classify sexuality into three patterns, two are males with XY chromosomes, called the the bracted :male (B ♂ ) with XYB and the leafy male (L ♂ ) with XYL, and the third pattern is female (♀) with XX. It was also reported that the bisexual plant with both male and female flowers occurs in the two patterns, other than B♂ . A bisexual intersex from L♂ is named " andromonoeclous " and another int-ersex from♀ named " gynomonoecious ".
