From Hermann Müller 23 October 1875
Summary
Is glad CD is working on cross- and self-fertilisation; reports recent works of botanists, notably Thomas Meehan’s ["Are insects any material aid to plants in fertilisation?", Philadelphia Press 13 Aug 1875], in which the importance of cross-fertilisation is denied.

From Hermann Müller 4 September 1876
Summary
Bombus mastrucatus, an alpine bee, conforms to his observations that B. terrestris breaks open the flowers of Trifolium pratense. However, in the Alps, B. terrestris does not behave this way.
Gentiana species are adapted to lepidopteran cross-fertilisation.

To Hermann Müller 1 January [1878]
Summary
Thanks HM for his review [of Forms of flowers, Kosmos 2 (1877–8): 286].
Thinks HM’s previous article was very important [Kosmos 2 (1877–8): 128–40]. CD will "heartily rejoice" if HM has explained the steps by which Rhamnus and Valeriana have been rendered dioecious.

From Hermann Müller 5 July 1878
Summary
Reports results of crosses between the two forms of Viola tricolor: 1. Female small flower crossed with male large flower yields all small flowers (cleistogamous self-fertilisation suspected); 2. Male small flower crossed with female large yields intermediate flowers; 3. Large flower crossed with large flower yields self-sterility symptoms.
