From J. D. Hooker [20 April 1860]
Summary
CD’s observations on curved styles read well. JDH seeks morphological rationale of curvature in the position of nectaries.
He has avoided lecturing to Royal Family’s children at Buckingham Palace.

From J. D. Hooker [28 April 1860]
Summary
Has examined Leschenaultia and concludes the external viscid surfaces have nothing to do with the stigmatic surface. Agrees with CD’s style and nectary conclusions; accounts for their form and position in irregular flowers by describing floral development.
[Enclosed are some queries by CD with answers by JDH. Gives information on seed setting by Mucuna
and an opinion on the abruptness of N. and S. limits of plant ranges.]

From J. D. Hooker 8 June 1860
Summary
Glad to hear good news of Etty [Henrietta Darwin].
CD’s observations on Scaevola are capital. The indusium collects the pollen and is the homologue of the pollen-collecting hairs of Campanula. A boat-shaped organ forms a second indusium, the inside base of which forms the stigmatic surface. The latter later protrudes as horns, forming the stigma.
Describes W. H. Harvey’s scientific career and thinks his letter interesting. Agrees with Harvey that the primary agency of natural selection is as great a mystery as ever. [Response to 2823.]

From J. D. Hooker [26 November – 4 December 1860]
Summary
Encourages CD’s work in vegetable physiology.
Ascending the Lebanon JDH noted limits of plant distribution as CD requested: lower limits of a genus sharper than upper. Sharpness of boundaries related to a plant’s moisture requirement.
Impressed by "sporadic" distribution at the Jardin des Plantes in Paris.

From J. D. Hooker 28 December 1860
Summary
CD’s article worth publishing in Gardeners’ Chronicle. JDH interprets CD’s observation in terms of selection. Has observed similar phenomenon in Cruciferae, where it can be taxonomically important.

From J. D. Hooker [11 May – 3 December 1860]
Summary
CD’s divergent series explains those anomalous plants that hover between what would otherwise be two species in a genus.
Inclined to see conifers as a sub-series of dicotyledons that developed in parallel to monocotyledons, but retained cryptogamic characters.
Mentions H. C. Watson’s view of variations.
Man has destroyed more species than he has created varieties.
Variations are centrifugal because the chances are a million to one that identity of form once lost will return.
In the human race, we find no reversion "that would lead us to confound a man with his ancestors".
