Abstract: In this study, the breeding system and the impact of population size on the process of sexual reproduction in Drosera intermedia were studied. This species was found to be autonomously selfing and even capable to produce seeds via pseudocleistogamous selfing. Artificial self-pollination did not reduce seed set nor germination in comparison to crosspollination, indicating that there is no inbreeding depression at these stages of the life cycle. Seed set per fruit did not depend significantly on population size. At a per plant basis, seed production was, however, significantly lower in small populations due to the fact that these individuals produced a lower number of flowers. The latter is likely due to reduced resource availability because of increased competition..
