Too sterile for any average.
Besides the experiments in the table, I fertilised a number of flowers without
particular care with their own two kinds of pollen, but they did not produce a
single capsule.
SUMMARY OF THE RESULTS.
LONG-STYLED FORM.
Twenty-six flowers fertilised legitimately by the stamens of corresponding
length, borne by the mid-and short-styled forms, yielded 61.5 per cent of
capsules, which contained on an average 89.7 seeds.
Twenty-six long-styled flowers fertilised illegitimately by the other stamens of
the mid-and short-styled forms yielded only two very poor capsules.
Thirty long-styled flowers fertilised illegitimately by their own-form two sets
of stamens yielded only eight very poor capsules; but long-styled flowers
fertilised by bees with pollen from their own stamens produced numerous capsules
containing on an average 21.5 seeds.
MID-STYLED FORM.
Twenty-four flowers legitimately fertilised by the stamens of corresponding
length, borne by the long and short-styled forms, yielded 96 (probably 100) per
cent of capsules, which contained (excluding one capsule with 12 seeds) on an
average 117.2 seeds.
Fifteen mid-styled flowers fertilised illegitimately by the longest stamens of
the short-styled form yielded 93 per cent of capsules, which (excluding four
capsules with less than 20 seeds) contained on an average 102.
