To Asa Gray   6 November [1862]

Summary

Agrees Max Müller’s book [see 3752] is interesting but cannot see how it will further his "cause".

A book by J. W. Colenso [The Pentateuch and book of Joshua critically examined, pt 1 (1862)] has just appeared and will "make a noise".

Would like some observations made on Cypripedium.

Will not publish yet on Lythrum as he must make many more crosses; the mid-styled is fertile with half of its own stamens.

Would like to try a few experiments on tendrils.

To Asa Gray   10–20 June [1862]

Summary

Thanks AG for praise of Orchids and his notes on several American species of orchid. Comments on AG’s observations.

Is experimenting [on dimorphism] with Rhexia and Melastoma.

Asks AG’s opinion of a paper by Thomas Meehan ["On the uniformity of relative characters between allied species of European and American trees", Proc. Philadelphia Acad. Nat. Sci. (1862): 10–13] which is the best case of the apparently direct action of the conditions of life CD has seen.

Requests postage stamp for his ill son [Leonard].

Thanks AG for observations on Cypripedium and gives recent observations of his own.

Arethusa is very pretty; structure seems like that of Vanilla.

Finds the little (so-called imperfect) flowers of Viola and Oxalis curious: the pollen-grains emit their tubes whilst within the anthers, and they travel in straight lines right to the stigmas.

Sympathises with events in the U. S.

Reports on French translation of Origin by Mlle C. Royer, "one of the cleverest & oddest women in Europe".

Alphonse de Candolle says he wants direct proof of natural selection; "he will have to wait a long time for that".

To Asa Gray   1 July [1862]

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.

To Asa Gray   14 July [1862]

Summary

Adaptations of orchid flowers. Believes the structure of all irregular flowers is adaptation to insect fertilisation.

Linum grandiflorum distinguishes its own pollen so that when placed on stigma of same flower the pollen-tube is not even exserted.

To Asa Gray   21 August [1862]

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.
