Title

Other claims from this paper (10)
- Observation Pins and thrums experienced disassortative, assortative and random pollination at different times in the season.
- Observation Homostyles were always assortatively pollinated.
- Association Morph frequency and the composition of stigmatic pollen loads were highly correlated among populations.
- Mechanism In anisoplethic populations, distyly seems to compensate for the rarity of one floral form by raising the proportion of compatible pollen received by the opposite form.
- Intervention effect Reciprocal placement of stigmas and anthers appears to increase compatible pollen grains received compared with homostyles.
- Observation Seed set in the six Menyanthes populations was always below the potential maximum.
- Association Among populations, the number of compatible pollen grains received was highly correlated with seed set.
- Association In at least one population, pollen availability was a major factor limiting seed set.
- Association Thrums set significantly more seeds per capsule than homostyles.
- Intervention effect Reciprocal placement of stigmas and anthers increased compatible pollen deposited on stigmas compared with homostylous flowers.
