These plants were measured to the tips of
their leaves on the 20th of October of the same year, and the eight
crossed plants averaged in height 8.4 inches, whilst the self-fertilised
averaged 8.53 inches, so that the crossed were a little inferior in
height, as 100 to 101.5. By the 5th of June of the following year these
plants had grown much bulkier, and had begun to form heads. The crossed
had now acquired a marked superiority in general appearance, and
averaged 8.02 inches in height, whilst the self-fertilised averaged 7.31
inches; or as 100 to 91. The plants were then turned out of their pots
and planted undisturbed in the open ground. By the 5th of August their
heads were fully formed, but several had grown so crooked that their
heights could hardly be measured with accuracy. The crossed plants,
however, were on the whole considerably taller than the self-fertilised.
In the following year they flowered; the crossed plants flowering before
the self-fertilised in three of the pots, and at the same time in Pot 2.
The flower-stems were now measured, as shown in Table 4/29.
