Summary:
Questions on breeding of plants: variation in established versus new varieties; predominance of wild species and old varieties when crossed with newer forms; predominance of males versus females; correlations between ease of hybridisation and tendency to vary and undergo cultivation; reversion; correlations between hybridisation and geographic distribution.
In WH’s Amaryllidaceae [1837], does he intend to say crossing is inimical to fertility?
