Although hand-pollinated Polemonium foliosissimum flowers set significantly more seeds than did either set of control blossoms, results suggest that individual reproduction (ie the total number of seeds produced by a plant) was limited by resources other than pollen. Pollen availability may also have limited seed production, but to a lesser extent. -from Authors
