JDH cannot abide CD’s connection of wide-ranging species and "highness". Australian flora contradicts this in many ways.

Relieved by Wallace’s letter.
At work on introductory essay to Flora Tasmaniae.
European plants naturalised in Australia are almost all adapted to invading disturbed ground.
JDH supports Asa Gray against Alphonse de Candolle as foreign member of Royal Society.
Outlines the basic categories of phanerogams.
Places Gymnospermae in the dicotyledons.
Evaluates the variable utility of embryological characters in plant classification.
Lyell has been strongly urging John Murray to publish CD’s book [Origin]. JDH feels Lyell overestimates the public interest in such works.
Gives examples of plants showing most marked varieties on the edge of their range.
JDH’s congratulations on Origin.
Lyell believes S. P. Woodward wrote review in Athenæum.
Lyell’s and Huxley’s positive responses.
JDH has only plunged into a few chapters.
JDH half through Origin. High praise for facts and reasoning.
Lyell told JDH his criticisms: small matters JDH did not appreciate.
Reactions of G. Bentham, J. S. Henslow, and C. C. Babington.
Forwards letter from Asa Gray.
Bentham is very agitated by Origin. CD over-emphasises natural selection. His theory accounts for too much and would be improved by unburdening it of natural selection.
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.
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.]
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.]
JDH reports on the debate on the Origin at Oxford [BAAS] meeting.
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.
JDH’s page-by-page criticisms on Origin, first edition, as requested by CD for preparation of the third edition.
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.
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".
List of Australian plants that have become naturalised in the Nilgiris [India] and are turning out the native trees.
Sends plant specimens. William Borrer will be glad to send seeds.
Asks CD whether he hears from Asa Gray. JDH’s opinion of the crisis [Trent case, Nov 1861] and the American Civil War.
Julius von Haast alludes to glacial drift in Middle Island of New Zealand.
Backwardness of JDH’s son, Willy.
Encloses a reference from Daniel Oliver which may be useful.
Glad CD has given up on Acropera ovules.
Doubts phanerogams less different in extreme forms [than Crustacea].
No systematic parallelism between plants and animals.
Offers list of Arctic plants with their colours. Asks CD whether it is useful to add colour to [descriptions of] plants.
Will send an Arethusa; offers other specimens.
Dimorphism.
Falconer contradicts Sumatra and Ceylon elephant story.
Lyell as rabid as ever about America.
