CD is led to believe there are no true permanently inbreeding, sexually reproducing beings. Thanks for replies to breeding questions.

Asks for clarification of Hippeastrum crosses: is selfing or crossing with individual of same species intended and was increased fertility due to constitution of foreign parent or due to the pollen coming from another plant? Has WH known any hybrid or mongrel to revert or to vary in a manner unlikely to be effect of soil?

Sends Journal of researches.

Summary

Rejects necessity of outbreeding and any general law of reversion.

Describes further experiments with Hippeastrum showing greater fertility with foreign pollen than with individual’s own pollen or with pollen from another individual of same species.
