Column 1: Source of Pollen-grains. Column 2: Minimum diameter. Column 3: Maximum diameter.
From the: Longest stamens of short-styled form : 15 to 16. Mid-length stamens of short-styled form : 12 to 13. Longest stamens of mid-styled form : 16. Shortest stamens of mid-styled form : 11 to 12. Mid-length stamens of long-styled form : 14. Shortest stamens of long-styled form : 12.
Therefore the extreme difference in diameter is as 16 to 11, or as 100 to 69; but as the measurements were taken at different times, they are probably only approximately accurate. The results of my experiments in fertilising the three forms are given in Table 4.29.

Long-styled by pollen of longest stamens of short-styled. Legitimate union : 19 : 15 : 57.4.
Long-styled by pollen of longest stamens of mid-styled. Legitimate union : 4 : 3 : 59.0.
Long-styled by pollen of own-form mid-length stamens. Illegitimate union : 9 : 2 : 42.5.
Long-styled by pollen of own-form shortest stamens. Illegitimate union : 11 : 0 : 0.
Long-styled by pollen of shortest stamens of mid-styled. Illegitimate union : 4 : 0 : 0.
