• Sexual dimorphism in flower production and cost of reproduction were examined in a natural population of the dioecious shrub Lindera umbellata THUNB. Sex ratios of flowering stems and flowering stools were not significantly different from 1 : 1. Male flowers were bigger than female flowers. The number of flowers per inflorescence did not differ between males and females, but males produced more floral buds than females. Cost of reproduction was examined in terms of the effect of flower and fruit production on subsequent flower production at shoot level. The effect of flower production did not differ between males and females, but fruit production by females appeared to have a direct negative effect on subsequent floral bud production. This suggests that the differential cost of sexual reproduction between the sexes affects sexual dimorphism in flower production by L. umbellata.
