11. Phaseolus multiflorus.
The five crossed plants were to the five self-fertilised in height as
100 to 96. Although the crossed plants were thus only four per cent
taller than the self-fertilised, they flowered in both pots before them.
It is therefore probable that they had some real advantage over the
self-fertilised plants.
12. Adonis aestivalis.
The four crossed plants were almost exactly equal in height to the four
self-fertilised plants, but as so few plants were measured, and as these
were all "miserably unhealthy," nothing can be inferred with safety with
respect to their relative heights.
13. Bartonia aurea.
The eight crossed plants were to the eight self-fertilised in height as
100 to 107. This number of plants, considering the care with which they
were raised and compared, ought to have given a trustworthy result. But
from some unknown cause they grew very unequally, and they became so
unhealthy that only three of the crossed and three of the
self-fertilised plants set any seeds, and these few in number. Under
these circumstances the mean height of neither lot can be trusted, and
the experiment is valueless. The cross-fertilised flowers on the
parent-plants yielded rather more seeds than the self-fertilised
flowers.
14. Thunbergia alata.
The six crossed plants were to the six self-fertilised in height as 100
to 108. Here the self-fertilised plants seem to have a decided
advantage; but both lots grew unequally, some of the plants in both
being more than twice as tall as others.
