(Author"s abstract). The size of seeds in capsules resulting from pollinations using self pollen from within the same inflorescence or from another inflorescence of the same plant and from naturally outcrossed flowers were compared... ...the ratio of large to small seeds and endosperm width was consistent within each of the three groups but differed significantly between them. Self pollination from the same inflorescence produced many small seeds and the fewest large seeds. These had the least endosperm.

Self-pollination between inflorescences of the same plant produces more large seeds with intermediate amounts of endosperm.

Naturally outcrossed flowers produced mainly large seeds and these had the most endosperm.
