"The Different Forms of Flowers on Plants of the Same Species"

Each capsule contained, on an
average, 81.3 seeds.
TABLE 4.25.2. Legitimate union.
13 flowers fertilised by the shortest stamens of the mid-styled. These stamens
equal in length the pistil of the short-styled.

61 percent of the flowers yielded capsules. Each capsule contained, on an
average, 64.6 seeds.

(4/7. *I suspect that by mistake I fertilised this flower in Table 4.25.6 with
pollen from the shortest stamens of the long-styled form, and it would then have
yielded about 64 seeds. Flowers to be thus fertilised were marked with black
silk; those with pollen from the mid-length stamens of the short-styled with
black thread; and thus probably the mistake arose.
