    • ‘Furthermore, behavioral data reveal that pollen collection commonly is followed by geitonogamous pollination.’
    • ‘This indicates that frequent geitonogamous selfing occurs.’
    • ‘Consequently, it reduces male fitness because geitonogamous pollen grains are barred from fertilizing ovules.’
