Asks D. Beaton whether varieties of the same species of Compositae frequently cross by insect agency or other means. Do the raisers of hollyhocks have to keep each variety separate for raising seed?

To Journal of Horticulture [before 18 June 1861]
Summary
CD, commenting on a case of peloric flowering in Auricula, urges readers to send in their observations on whether flowers nearest the axis tend to differ from others on the plant. Such a law of variation would be worth discovering.

To Journal of Horticulture [17 May 1861]
Summary
Thanks Mr Beaton for his answer [to 3147].
Asks further questions on points raised in Beaton’s previous papers: whether crossing white and blue varieties of Anemone apennina produced many pale shades; whether the Mathiola incana and M. glabra which crossed freely were artificially or naturally crossed.
CD is delighted by Beaton’s assertion that "not a flower in a thousand is fertilised by its own immediate pollen".
Recounts his experiments with Leschenaultia formosa to show insect fertilisation.
