Four out of twelve capsules, spontaneously self-fertilised at
the same time, were found to contain no good seeds; and the remaining
eight contained on an average 6.6 seeds per capsule. But it should be
observed that later in the season the same plants produced under a net
plenty of very fine spontaneously self-fertilised capsules.
The above two lots of seeds, after germinating on sand, were planted in
pairs on opposite sides of five pots. The two lots of seedlings, when
half an inch in height, and again when 6 inches high, were measured to
the tips of their leaves, but presented no difference. When fully grown,
the flower-stalks were measured to the summits of the seed capsules,
with the following result:--
TABLE 4/33. Papaver vagum.
Heights of flower-stalks to the summits of the seed capsules measured in
inches.
