two white-flowered plants the pistil projected above the stamens, but in one of
them it was longer and had a more elongated and rougher stigma, than in the
other; and the pollen-grains from the latter were to those from the plant with a
more elongated pistil only as 100 to 88 in diameter, instead of as 100 to 57.
The corolla of the long-styled and short-styled form differs in shape, in the
same manner as in P. veris. The long-styled plants tend to flower before the
short-styled. When both forms were legitimately fertilised, the capsules from
the short-styled plants contained, on an average, more seeds than those from the
long-styled, in the ratio of 12.2 to 9.3 by weight, that is, as 100 to 78. In
Table 1.10 we have the results of two sets of experiments tried at different
periods.

Column 1: Nature of the Union.
Column 2: Number of Flowers fertilised.
Column 3: Number of good Capsules produced.
Column 4: Average Weight of Seeds per Capsule.
...
Column 5: Average Number of Seeds per Capsule as ascertained on a subsequent
occasion.

Long-styled by pollen of short-styled. Legitimate union :
24 : 16 : 0.58 :: 50.

Long-styled by own-form pollen. Illegitimate union :
20 : 13 : 0.45 :: 35.

Short-styled by pollen of long-styled. Legitimate union:
8 : 8 : 0.76 :: 64.
