The effect of plant size on phenotypic gender and functional gender was studied within a population of a hermaphroditic perennial herb. Anemone debilis, which had only one perfect flower on a plant. Seed-set under natural conditions was 69-89%, and the selfing rate by autodeposition was 49% of maximum possible seed-set. Phenotypic gender calculated from the stamen and ovule numbers changed with individual flower size measured by dry weight ; large plants having larger flowers allocated more to female function (ovule number) than small plants. Matured seed number increased linearly with flower size, whereas estimated sired seed number indicated a saturating pattern. Functional gender calculated from the produced seed number and the estimated sired seed number changed with flower size, where large plants succeeded relatively better as mother plants and some small plants succeeded as pollen donors only. Thus, size-dependent sex allocation between the male and female functions at a flowering stage seemed to reflect the paternal and maternal success for seed production.
