Seeds: worried they will turn into another barnacle job.

Studies plants colonising abandoned field.

Experiment on plant sleep movements.

CD objects to "Atlantis" because no evidence; does not affect species theory.

Finds Forbes’s continental theories, migration, and double creation are all unsatisfactory explanations of geographical distribution of plants.

Is currently working on problems of sea transport of plant species.

European plants on Australian Alps only explicable by double creations.

Detailed response to JDH’s critique of sea transport and continental connection theories. JDH’s claim that low plants are widely distributed fits both theories.

Species theory does not touch origin of life.

Thanks for Hedysarum.

Pleasure in identifying field plants.

On the transport of fish eggs by the water-beetle Dytiscus marginalis.

Has used borrowing rights at Linnean Society Library arranged for him by JDH.

Discusses hybrid plants he has raised, particularly hybrids between Geum urbanum and G. rivale, which are very fertile and exhibit great variability. [See Natural selection, p. 102.]

Asks whether JSH considers Lychnis diurna and L. vespertina species or varieties.

Asks for help with his work on hybrids.

Would like JSH to go over London catalogue of British plants, marking "close species", i.e., those he considers real species but which are very closely allied. Withholds his motive as it might influence the result.

Has found Agrostis with worms in every germen and no stamens on stigma.

Now has 46 kinds of peas all growing together.

Red and white campions: JSH regards them as races, not species; a flesh-coloured intermediate exists.

Sends a list of "close" species from his Manual of botany.

Hopes Hooker or CD will write an essay on species. Discusses some of the difficulties of defining botanical species.

Sends a list of plants with stamps to pay the Hitcham girls who will collect seeds for him.

Describes his work with seeds in salt water.

For his experiments he would like seeds collected from plants that grow both near Hitcham and in the Azores.

Explains again what JSH should do in marking "close species".

Answers queries on Azores fauna and flora.

Notes on the interbreeding of different races of silkworm. [Forwarded with explanatory note by Edward Blyth.]

Has named 35 species of grasses.

Seed-salting continues.

Thanks JSH for seeds.

Clarifies his request about marking [London] catalogue [of British plants] – JSH is to mark those he thinks really are species, but which are very closely allied to some other species.
