• Size-specific effects on the resource allocation pattern and gender variation at the flowering stage were studied in a perennial hermaphrodite, Anemone debilis. With an increase of plant size, allocations to inflorescence and roots decreased, while those to leaves and stem were constant ; allocations to rhizome increased. A negative correlation between sexual reproduction and survival or vegetative reproduction was suggested. There was a trade-off in resource allocation between male function (androecium) and female function (gynoecium) within an inflorescence. Gender of A. debilis gradually shifted to femaleness with size increment. This size-specific sex allocation pattern agrees with the prediction of the theoretical model for entomophilous hermaphroditic plants.
