Short-styled by own-form pollen. Illegitimate union :
7 : 4 : 0.23 :: 25.

SUMMARY:

The two legitimate unions together :
32 : 24 : 0.64 :: 57.

The two illegitimate unions together :
27 : 17 : 0.40 :: 30.

The fertility, therefore, of the two legitimate unions together to that of the
two illegitimate unions, as judged by the proportional number of flowers which
yielded capsules, is as 100 to 84. Judging by the average weight of seeds per
capsule produced by the two kinds of unions, the ratio is as 100 to 63. On
another occasion a large number of flowers of both forms were fertilised in the
same manner, but no account of their number was kept. The seeds, however, were
carefully counted, and the averages are shown in the right hand column. The
ratio for the number of seeds produced by the two legitimate compared with the
two illegitimate unions is here 100 to 53, which is probably more accurate than
the foregoing one of 100 to 63.
