To J. D. Hooker   6 October [1862]



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.

From J. D. Hooker   [12 October 1862]



Has sent two Impatiens flowers; curious to know what CD makes of the floral whorls and their vascular bundles.

Cassia is another genus that has different [coloured] anthers in same flower.

Continues to work on Welwitschia.

Feels as CD does about his work, which after a time seems flat and stale. He could never have done what CD did in his Orchids.

CD’s facts about Verbascum have horrible bearing on JDH’s practice of lumping species together.

Thanks for Aldrovanda reference and Cassia.

Has wasted labour on Melastomataceae without getting a glimpse of the meaning of the parts.

Wants seeds, from their native land, of Heterocentron or Monochaetum.

Is beginning to change his view about rarity of natural hybrids.

From J. D. Hooker   [18 October 1862]



Does CD want Masdevallia?

Sends addresses of persons in S. America who would send Melastomataceae seeds.

Has ordered Matthieu Bonafous on maize [Histoire naturelle du maïs (1836)].

From J. D. Hooker   25 October 1862



Has sent Masdevallia and other plants.

J. J. F. W. v. Parrot’s Ararat [(1834), trans. W. D. Cooley, in The world surveyed in the XIXth century, vol. 1 (1845)] refreshing in its simple faith in the ark.

To J. D. Hooker   27 [October 1862]



Masdevallia turns out to be nothing wonderful, "I was merely stupid about it."

Asks for plants for experiments.

Hedysarum and Oxalis sensitiva seeds.

Asks whether Oliver knows of experiments on absorption of poisons by roots.

CD finds he cannot publish this year on Lythrum salicaria; he must make 126 additional crosses!

Asks for odd variations of common potato; he wants to grow a few plants of every variety.

Variation is crawling.

Has had some bad attacks lately.
