To J. D. Hooker 6 October [1862]
Summary
Thanks for opinion on Drosera. After working for a time on a subject he is absolutely incapable of judging its value.
Has found a case in Lythrum of a necessary triple alliance between three hermaphrodites; the strangest case of propagation recorded among plants or animals.
Asks for L. thymifolia to see how a trimorphic form passes or graduates into dimorphic.
Questions JDH on Linum perenne.
Has found 33 hybrids in one field between Verbascum thapsus and V. lychnitis. The perfect series of varieties would have justified running the species together, but every one of the intermediate forms is sterile.

- … J. D. Hooker, 1 May [1862] . Hooker read a paper entitled ‘On the vegetation of the Cameroons’ at a meeting of the Linnean Society of London on 5 June 1862 ( Journal of the Proceedings of the Linnean Society of London (Botany) 6 (1862): cvi). This paper was not published by the society; a further paper by Hooker on the topic was read the following year and published in 1864 ( …
To John Scott 19 December [1862]
Summary
JS should be proud of his paper ["Nature of the fern-spore", Edinburgh New. Philos. J. 2d ser. 16 (1862): 209–27].
CD has just found that JS’s observations on the confluence of two sexes causing variability were independently confirmed by Huxley.
CD has always suspected a fundamental difference between buds and ovules.
Asks for examples of "bud-variation" or "sports".
Asks JS to test germination of pollen on rostellum of Laelia.
Offers JS money for experimental supplies, e.g., netting, to keep insects out of flowers.
Encloses an outline of crossing experiments with Lythraceae, Primula, Pelargonium, and others, which he feels would be valuable.
Note on melastomids.

- … Hooker, 14 [October 1862] . In the letter to J. D. Hooker, 14 [October 1862] , CD asked Hooker for the names of people to whom he could apply for seeds of Heterocentron or Monochaetum in their native South America. The reference is to Richard Spruce . The nursery of Messrs Herbst & Co . was probably established by Hermann Carl Gottlieb Herbst . Although CD wrote to Spruce to ask him for information concerning the Melastomataceae ( see letter from A. R. Wallace, 2 January 1864 ( …

There are a number of notes in DAR 27.2 recording the details of crossing experiments carried out by CD on this species in the summer of 1862; the earliest is dated 31 July 1862 (DAR 27.2 (ser. 2): 7). CD’s paper on the three forms in Lythrum ( ‘Three forms of Lythrum salicaria ’ ) was read before the Linnean Society of London on 16 June 1864. …
To J. D. Hooker 24 [November 1862]
Summary
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.

- … 1864 are in DAR 27.2B; his later work on Lythrum is in DAR 109. In 1862, as CD was counting the seeds resulting from his crosses of Lythrum salicaria , he grew increasingly confident that each of the three forms (long-styled, mid-styled, and short-styled) were hermaphrodites, and together included three females and three males (see Correspondence vol. 10, letter to J. D. Hooker, …
