Hence the plant yielded 61 per cent of the full complement
of seeds.
PLANT 10.
This long-styled plant was freely fertilised at the same time and in the same
manner as the last. Ten capsules yielded an average of 44.2 seeds, with a
maximum of 69 and a minimum of 25; hence this plant yielded 47 per cent of the
full complement of seeds.]
The nineteen long-styled plants of the third lot, of the same parentage as the
last lot, were treated differently; for they flowered during 1867 by themselves
so that they must have been illegitimately fertilised by one another. It has
already been stated that a legitimate long-styled plant, growing by itself and
visited by insects, yielded an average of 21.5 seeds per capsule, with a maximum
of 35; but, to judge fairly of its fertility, it ought to have been observed
during successive seasons. We may also infer from analogy that, if several
legitimate long-styled plants were to fertilise one another, the average number
of seeds would be increased; but how much increased I do not know; hence I have
no perfectly fair standard of comparison by which to judge of the fertility of
the three following plants of the present lot, the seeds of which I counted.
[PLANT 11.
This long-styled plant produced a large crop of capsules, and in this respect
was one of the most fertile of the whole lot of nineteen plants.
