It yielded an average, from ten capsules, of 83.5 seeds, with a maximum
of 110 and a minimum of 64, thus attaining 64 per cent of the normal fertility.
During the highly favourable year 1866, it was freely and legitimately
fertilised by illegitimate plants belonging to the present Class and to Class 5,
and yielded an average, from eight capsules, of 86 seeds, with a maximum of 109
and a minimum of 61, and thus attained 66 per cent of the normal fertility. This
was the plant with some of the anthers of the longest stamens contabescent as
above mentioned.
PLANT 27.
This mid-styled plant, fertilised during 1864 in the same manner as the last,
yielded an average, from ten capsules, of 99.4 seeds, with a maximum of 122 and
a minimum of 53, thus attaining to 76 per cent of the normal fertility. If the
season had been more favourable, its fertility would probably have been somewhat
greater, but, judging from the last experiment, only in a slight degree.
PLANT 28.
This mid-styled plant, when legitimately fertilised during the favourable season
of 1866, in the manner described under Number 26, yielded an average, from eight
capsules, of 89 seeds, with a maximum of 119 and a minimum of 69, thus producing
68 per cent of the full number of seeds. In the pollen of both sets of anthers,
nearly as many grains were small and shrivelled as sound.
