Several flowers on this
plant were crossed with pollen from other flowers on the same plant, and
several other flowers were fertilised with their own pollen. The seed
thus produced was allowed to germinate on bare sand; and the seedlings
were planted in the usual manner on the opposite sides of six pots. All
the remaining seeds, whether or not in a state of germination, were sown
thickly in Pot 7; the three tallest plants on each side of this latter
pot being alone measured. As I was in a hurry to learn the result, some
of these seeds were sown late in the autumn, but the plants grew so
irregularly during the winter, that one crossed plant was 28 1/2 inches,
and two others only 4, or less than 4 inches in height, as may be seen
in Table 3/21. Under such circumstances, as I have observed in many
other cases, the result is not in the least trustworthy; nevertheless I
feel bound to give the measurements.

same Plant.
Column 3: Plants raised from Flowers fertilised with their own Pollen.
