The ratio of male : female gametophytic plants from all of the three stations was approximately 1:1 during the early sampling period, these ratios changed at the end of the growing season. The ratio of gametophytic : tetrasporic plants of materials collected from the three stations showed markedly different pattern during the growing period.},
