(5/7. Dr. Hildebrand, who first called attention to this subject 'Botanische
Zeitung' 1864 page 5, raised from a similar illegitimate union seventeen plants,
of which fourteen were long-styled and three short-styled. From a short-styled
plant illegitimately fertilised with its own pollen he raised fourteen plants,
of which eleven were short-styled and three long-styled.) These plants grew
vigorously; but the flowers in one instance were small, appearing as if they had
reverted to the wild state. In the first illegitimate generation they were
perfectly fertile, and in the second their fertility was only very slightly
impaired. With respect to the short-styled plants, twenty-four out of twenty-
five of their illegitimate offspring were short-styled. They were dwarfed in
stature, and one lot of grandchildren had so poor a constitution that four out
of six plants perished before flowering. The two survivors, when illegitimately
fertilised with their own-form pollen, were rather less fertile than they ought
to have been; but their loss of fertility was clearly shown in a special and
unexpected manner, namely, when legitimately fertilised by other illegitimate
plants: thus altogether eighteen flowers were fertilised in this manner, and
yielded twelve capsules, which included on an average only 28.5 seeds, with a
maximum of 45.
