Many of our common wild flowers, as perfectly and effectually planned for cross-fertilization as the orchids, do retain the reserve power of final self-fertilization if unfertilized by foreign pollen.
What an immediate and expressive welcome! The nectary now drained of its sweets, the moth creeps or flutters to a second blossom, and its pollen-dusted body thus coming in contact with its stigma, cross-fertilization is accomplished.
They may be smothered out by the adverse force of superior numbers; they are even more likely to be bred out of existence by unprevented cross-fertilization, or to disappear from mere change of fashion. The question, however, is not so much about reversion to an ancestral state, or the falling off of a high-bred stock into an inferior condition.
Aristotle, three hundred years before Christ, had suggested that, by cross-fertilization and change of environment, new species had been and were being evoked.
