Delayed stigma receptivity in Collinsia heterophylla (Plantaginaceae): Genetic variation and adaptive significance in relation to pollen competition, delayed self-pollination and mating-system evolution
To increase our knowledge about mating-system evolution, we need to understand the relationship between specific floral traits and mating system. Species of Collinsia (Plantaginaceae) vary extensively in mating system; this variation is associated with variation in floral morphology and development and with the timing of self-pollination. Counterintuitively, large-flowered, more outcrossing specie
