A northern Swedish population of Bartsia alpina (Scrophulariaceae), an arctic-alpine, perennial plant pollinated by long-tongued bumble bees (Bombus balteatus and B. pascuorum), was found to have a mixed mating system. Although self-compatible, self-pollination did not occur without pollinator intervention. Full normal seed set was reached after a single pollination. Pollinations occurring early and late in the season, when Bartsia populations were less dense, enhanced gene flow substantially. |
