Poa annua shows putative evidence of nectar secretion in grasses. He will continue observations as CD requests.
Reports on insects fertilising Viola tricolor and on the fertilisation of the two wild forms [see Cross and self-fertilisation, p. 124 n., 125].
Sends a note on R. Caspary’s observations of Corydalis self-fertilisation [see Cross and self-fertilisation, p. 331].
Has begun his experiments on the self- and cross-fertilised flowers.
Fritz Müller is now working on the Brazilian honey-bees (Melipona and Trigona).
HM thanks CD for fertilisation references.
Feels CD’s and Fritz Müller’s judgments on his "Anwendung" essay [see 8313] are of highest value. Mentions some of FM’s comments.
Looks forward to second English edition of Descent.
On HM’s Befruchtung der Blumen [1873].
Comments on Fritz Müller’s article on Hedychium.
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.
Writing on vegetable physiology.
Nothing in CD’s life has ever interested him more than the fertilisation of such plants as Primula and Lythrum.
Has just heard that HM has been treated shamefully by his Government. What has happened?
Interested that HM is studying structure of insects in relation to flowers.
Comments on HM’s book [Die Befruchtung der Blumen (1873)]. Particularly glad to read historical sketch and discussion of work of C. K. Sprengel.
