- Title
Testing sex-allocation theory: flowers vs seeds in hermaphrodite plants.

- Abstract
Plants of the self-compatible Echium vulgare and Cynoglossum officinale frequently abort seeds, while all flowers contain pollen. Sex allocation then changes with the seed to flower ratio. Based on our field data, we can draw fitness sets. The analysis shows that the fitness set is bowed out and that hermaphroditism is evolutionarily stable in both species. It also predicts correctly the size-dependent pattern of seeds per flower observed in C. officinale in the field, where small plants produce 0.39 and large plants 0.85 seeds per flower. The model fails to predict the pattern in E. vulgare .
