Lythrum salicaria. Short-styled form, fertilised by own-form pollen : 1 : 0 : 8.
Lythrum salicaria. Short-styled form, fertilised by pollen from mid-length
stamens of long-styled form : 4 : 0 : 8.
Lythrum salicaria. Mid-styled form, fertilised by own-form pollen : 1 : 3 : 0.
Lythrum salicaria. Mid-styled form, fertilised by pollen from shortest stamens
of long-styled form : 17 : 8 : 0.
Lythrum salicaria. Mid-styled form, fertilised by pollen from longest stamens of
short-styled form : 14 : 8 : 18.
Oxalis rosea. Long-styled form, fertilised during several generations by own-
form pollen, produced offspring in the ratio of : 100 : 0 : 0.
Oxalis hedysaroides. Mid-styled form, fertilised by own-form pollen : 0 : 17 :
0.
We see in these two tables that the offspring from a form illegitimately
fertilised with pollen from another plant of the same form belong, with a few
exceptions, to the same form as their parents. For instance, out of 162
seedlings from long-styled plants of Primula veris fertilised during five
generations in this manner, 156 were long-styled and only 6 short-styled. Of 69
seedlings from P. vulgaris similarly raised all were long-styled. So it was with
56 seedlings from the long-styled form of the trimorphic Lythrum salicaria, and
with numerous seedlings from the long-styled form of Oxalis rosea.
