Delayed thanking JL for two notes until he heard from Hooker about Acropera luteola; had no idea A. luteola was not a well-known name.
Cites his reasons for identifying A. loddigesii as male; hopes for a Gongora flower from Hooker which, JL suggested, may be the female.
Thanks JL for information about Acropera luteola.
Also thanks for the Gongora; cannot avoid the impression it is male.
Undated letter of four pages over 1 folio.
Asks GB’s help to clear up discrepancies between his and John Lindley’s observations on pollination of Melastomataceae.
Returns Asa Gray’s letter. Disappointed with Gray. Comments on America. British–American relations.

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.

Thanks JL for review [of Orchids, Gard. Chron. (1862): 789–90, 863]; CD published almost by accident, having been led on in part by encouragement from JL.
Asks for reference to GB’s summary of Targioni-Tozzetti’s book ["Historical notes on the introduction of various plants into the agriculture and horticulture of Tuscany: a summary of a work entitled Cenni storici sulla introduzione di varie piante nell agricultura ed orticultura Toscana by Dr Antonio Targioni-Tozzetti, Florence, 1850", J. Hortic. Soc. Lond. 9 (1855): 133–81]. [See Variation, 1st ed., 1: 306 n.]

JDH hopes to send Asa Gray copies of GENERA PLANTARUM with the autumn box of 'distributa'. JDH discusses Sir John William Dawson's criticisms of one of his essays concerning plant distribution [possibly JDH's introductory essay from FLORA ANTARCTICA], addressing each point in detail. Dawson's objections centre on the flora of Scandinavia & supposed geological inaccuracies, many concerning Greenland. In the past JDH & Sir Charles Bunbury have quashed some of Dawson's palaeobotany papers sent to the Geological Society. JDH is convinced his own conclusions are sound, they have the support of James Hector & Sir Charles Lyell. Dawson is against Darwinism & the theory of evolution by natural selection. JDH notes that there is currently a lot of changes in geological theory & hypotheses in the discipline are difficult to prove, there is an argument about the effectiveness of current species variation & distribution in determining past land formations. JDH believes geological & biological evidence must both be taken into account to form a strong hypothesis. He makes the point that all facts began as theory, just as absolute specific creation is now questioned so may creation by variation be disproved, or it could become established fact. JDH mentions his own work on Welwitschia [mirabilis], specifically characteristics of ovules in male & female flowers, & Gray's work on Cypripedium. Thanks Gray for Asimina & urges him to write a systematic resume of American flora.

Sends Asa Gray letter: "nearly as mad as ever in our English eyes".
Bates’s paper is admirable. The act of segregation of varieties into species was never so plainly brought forth.
CD is a little sorry that his present work is leading him to believe rather more in the direct action of physical conditions. Regrets it because it lessens the glory of natural selection and is so confoundedly doubtful.
JDH laid too much stress on importance of crossing with respect to origin of species; but certainly it is important in keeping forms stable.
If only Owen could be excluded from Council of Royal Society Falconer would be good to put in. CD must come down to London to see what he can do.
Falconer’s article in Journal of the Geological Society [18 (1862): 348–69] shows him coming round on permanence of species, but he does not like natural selection.
Sends Lythrum salicaria diagram.
