Summary

Observations on Platanthera.

Possibility of trimorphism in Mertensia.

Summary

AG’s "capital" review of Orchids [Am. J. Sci. 2d ser. 34 (1862): 138–44].

Thinks there are three forms of Lythrum salicaria.

Discusses transport of seeds by sea.

Summary

AG’s orchid observations are admirable.

Owen has lectured on birds’ descending from one form.

French criticism of CD’s Primula paper.

Only AG has seen that Orchids was "a ""flank movement"" on the enemy".

Summary

Gives J. T. Rothrock’s observations on the structure and fertility of the two forms of Houstonia. Mentions his own observations on Rhexia virginica and Gymnadenia tridentata.

Summary

Thanks for notes on Cypripedium and Platanthera hookeri, which is really beautiful and quite a new case.

His son, George, has been observing the insect fertilisation of orchids.

CD has been crossing peloric flowers of Pelargonium, but doubts he will get good results with respect to sterility of hybrids.

Rhexia glandulosa does not appear to be dimorphic. Lythrum is trimorphic.

Summary

Discusses dimorphic plants and the occurrence of "precocious fertilisation" in the bud.

Gives some comments on design in nature in the light of the translator’s commentary in the French edition of the Origin.

Reports the recent events of the Civil War.

[Note on verso of envelope:] Utricularia vulgaris is "about as neatly contrived for cross-fertilisation by insects as almost any orchid".

Summary

Has not had time to look at Rhexia.

Progress of Civil War.

Summary

Is sending first half of orchid book.

Feels he is wrong about Melastoma.

Summary

Emma and Leonard have scarlet fever.

Houstonia seems "a grand case"; J. T. Rothrock should publish his observations on the two pollens and the reciprocal action of two hermaphrodites.

Rhexia glandulosa offers nothing odd, but Heterocentron will turn out something marvellous like Lythrum.

Would like to know what AG thinks of last chapter of Orchids.

Summary

Lythrum salicaria is coming out clear.

Would be glad of Nesaea seed.

Is disappointed with Melastoma, but is sure there is something curious to be made out.

His experiments with poisons on Drosera lead him to conclude that it possesses something analogous to nervous matter.

Comments on natural hybrids of Verbascum.

Deplores the Civil War and the feelings it has fostered in Britain.

Summary

Encloses stamps for Leonard Darwin.

Summary

Gives reference to his observations on tendrils [Proc. Am. Acad. Arts & Sci. 4: 98–9].

Notes cases in which the pollen of the fertilising plant affects the form of the fruit of the fertilised plant, e.g., gourds and maize.

Discusses the Civil War and the attitudes of the English press.

Summary

Discusses AG’s article ["Dimorphism", Am. J. Sci. 2d ser. 34 (1862): 419–20]. Does not like the terms "dioecio-dimorphism" or "precocious fertilisation". Discusses the separation of sexes in plants; cannot doubt that hermaphroditism is the aboriginal state.

Discusses AG’s observations on orchids and his review of Orchids [Am. J. Sci. 2d ser. 34 (1862): 138–51].

Summary

Believes Lythrum is trimorphic. Asks AG for seeds of plants he suspects are polymorphic.

Summary

Last chapter of Orchids opens up a "knotty sort of question about accident or design".

Changes in orchid flowers as they age.

Thinks CD may find trimorphism in Nesaea verticillata.

Summary

Notes and observations on orchids.

Summary

Encloses maize seeds.

Has heard of a butterfly with pollinia of Platanthera stuck to it.

Comments on AG’s notes ["Dimorphism in the genitalia of flowers", Am. J. Sci. 2d ser. 34 (1862): 149–50].

"Precocious fertilisation".

Summary

Floral structure of Melastoma. Asks AG to observe position of pistils in lately-opened flowers of different plants.

Summary

AG has Cypripedium to send to CD.

Civil War and English feelings.

Summary

Gives some observations on changes in pistil position with age in Monochaetum. Asks whether AG can observe Rhexia for similar movements.

"One of the best men, though at present unknown", H. W. Bates, has taken up natural selection.
