Not one flower yielded a capsule.

Besides the experiments in Table 4.24, I fertilised a considerable number of mid-styled flowers with pollen, taken by a camel’s-hair brush, from both the longest and shortest stamens of their own form: only 5 capsules were produced, and these yielded on an average 11.0 seeds.

TABLE 4.25.1. Legitimate union.

12 flowers fertilised by the shortest stamens of the long-styled. These stamens equal in length the pistil of the short-styled.
