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.
Cites cases of leguminous plants whose cleistogamic flowers produce more seed than perfect flowers. [See Forms of flowers, p. 326.]
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.
Returns CD’s lists [sent with 2184]. Confusion in genera of Silene is great in continental botanic gardens. One would have to know whether C. F. v. Gärtner had the right names for species in his experiments.
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.
Asks GB to vote for "a distant connexion of mine" at Athenaeum, and to mention this to Hooker.
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.
Remarks about Labiatae, Linum, Oxalis and Viola occasioned by hearing CD’s paper ["Two forms of Primula", read 21 Nov 1861, Collected papers 2: 45–63].
Lists pairs of Oxalis species with differing proportions of stamens and styles.
Thanks GB for valuable letter [3331].
Will follow his suggestion about violets.
Discusses differences between Thymus and Primula.
Asks GB’s help to clear up discrepancies between his and John Lindley’s observations on pollination of Melastomataceae.
Will try to come to Linnean Society to read his paper, but has been "extra headachy". Fears his paper ["Sexual forms of Catasetum", Collected papers 2: 63–70] will not be worth Lindley’s attendance.
