"Effects of Cross and Self Fertilisation in the Vegetable Kingdom"

I expected that the seedlings from
this semi-self-sterile plant would have profited in a higher degree from
a cross, than did the seedlings from the fully self-fertile plants. But
my anticipation was quite wrong, for they profited in a less degree. An
analogous result followed in the case of Eschscholtzia, in which the
offspring of the plants of Brazilian parentage (which were partially
self-sterile) did not profit more from a cross, than did the plants of
the far more self-fertile English stock. The above two lots of crossed
and self-fertilised seeds from the same plant of Reseda odorata, after
germinating on sand, were planted on opposite sides of five pots, and
measured as in the last case, with the result in Table 4/39.

included, measured in inches.
