Do Silene species with exposed stigmas tolerate interference by heterospecific pollen?

Consistent with the tolerance hypothesis, our results indicated that species experiencing higher HP interference are likely to be tolerant to an increase of HP percent. These species with generalist-pollinated flowers and exposed large stigmas may benefit from an increase of conspecific pollen deposition, despite the associated increase in heterospecific pollen deposition.
