Asks GB to send him flowers of the two forms of Boronia pinnata, as he is republishing his papers on dimorphic plants [Forms of flowers].
Sends copy of Cross and self-fertilisation.
Has examined the specimens of Boronia pinnata. No evidence of two distinct bodies of individuals.
Asks whether extra-American species of Aegiphila are heterostyled.
Thanks GB for corrections to chapter on cleistogamic flowers [Forms of flowers].
Asks for his opinion on "bloom"-producing plants in different climates.
GB’s note has given him more pleasure than his election to the French Academy.
CD pleased to be of use to GB. He remembers his own work on orchids with pleasure. Thinks GB will be able to improve CD’s terminology for orchids.
Asks GB to sign certificate for Francis Darwin [candidate for Royal Society].
Asks GB to vote for "a distant connexion of mine" at Athenaeum, and to mention this to Hooker.
Asks GB for help in clearing up his problems about Leguminosae, in connection with his "wild bit of speculation on the crossing of plants" [see Natural selection, p. 71].
Thanks GB for information on Leguminosae, especially about those with apetalous flowers and almost without anthers.
Thanks GB for information on apetalous flowers. "The whole order [Leguminosae] will remain my detestable enemies."
Thanks GB for his help on naturalised plants; comments on spreading of plants.
Wants to quote GB on the names of species and varieties of Silene on which C. F. von Gärtner experimented.
Thinks GB will be disappointed in his book [Natural selection]. "It will be grievously too hypothetical."
For his studies on fertility of crosses, asks GB to mark a list of pairs of Cucubalus as to whether they are varieties of the same species, or distinct species.
Thanks GB for his answers [to 2184], which were as explicit as he expected. Cucubalus viscosus and italicus are extremely sterile together; all other forms extremely fertile. Other instances of infertility found by Gärtner.
At Hooker’s request, sends his copy of Gärtner [Bastarderzeugung (1849)], "shamefully scribbled over".
Asks for specimen of Orchis pyramidalis for his work on insect fertilisation of orchids.
Thanks GB for specimen [of Orchis pyramidalis].
Discusses a great difficulty with orchids: "Insects visit several species which never secrete an atom of honey." [See Orchids, p. 44ff.] Does GB know whether nectar is ever secreted and reabsorbed promptly?
Thanks GB for arranging for his paper ["Two forms of Primula", Collected papers 2: 45–63] and for his photograph.
Requests more precise details about Oxalis, to which GB referred in his remarks on Primula.
Would prefer to have Primula paper published in the Linnean Society’s Journal rather than Transactions.
Thanks GB for valuable letter [3331].
Will follow his suggestion about violets.
Discusses differences between Thymus and Primula.
