The average height of the four crossed plants is 33.5, and that of the
four self-fertilised plants 27.62 inches, or as 100 to 82. The crossed
plants altogether produced 105 and the self-fertilised plants 63
capsules; or as 100 to 60. In both pots a self-fertilised plant flowered
before any one of the crossed plants.
16. LOASACEAE.--Bartonia aurea.
Some flowers were crossed and self-fertilised in the usual manner during
two seasons; but as I reared on the first occasion only two pairs, the
results are given together. On both occasions the crossed capsules
contained slightly more seeds than the self-fertilised. During the first
year, when the plants were about 7 inches in height, the self-fertilised
were the tallest, and in the second year the crossed were the tallest.
When the two lots were in full flower they were measured, as in Table
5/63.
