Has gone over to CD’s side on the fertilisation of clover in New Zealand by bees.
Botanical practice can confuse CD’s compilations. Many small genera would have been species had the whole natural order [family] been known.
JDH’s low opinion of Buckle;
high opinion of Mrs Farrer.
Summary of JDH’s objections to CD’s survey of floras and conclusion that large genera vary more than small.
Continued objections to methods and conclusions of CD’s survey.
Reports that N. J. Andersson finds every European willow bar one is also American.
Has heard from David Livingstone and reports on his progress.
Sends proofs [of "On the tendency of species to form varieties … ", read 1 July 1858, Collected papers 2: 3–19]. CD could publish his abstract [later the Origin] as a separate supplemental number of [Journal of the Linnean Society].
JDH has studied in detail CD’s manuscript on variable species in large and small genera and concurs with its consequences. Discusses methodological idiosyncrasies of systematists, e.g., Bentham, Robert Brown, and C. C. Babington, which complicate CD’s tabulations.
The CD–Wallace paper has gone to press.
JDH’s tabulation of variable species from Bentham was done in haste.
Busy with introductory essay to [The botany of the Antarctic voyage, pt III] Flora Tasmaniae [printed separately as On the flora of Australia (1859)].
Now explains greater abundance of European species in Tasmania than in Fuegia by CD’s "refrigeration" hypothesis.
At work on the introductory essay to Flora Tasmaniae.
Discusses the effects of climate and geography on "vegetable strife".
Would appreciate loan of CD’s chapter on transmigration across tropics, which may help with the difficulties of Australian distribution.
Still regards plant types as older than animal types.
The Cape of Good Hope and Australian temperate floras cannot be connected by the highlands of Abyssinia.
JDH cannot abide CD’s connection of wide-ranging species and "highness". Australian flora contradicts this in many ways.

JDH characterises himself to Asa Gray as a full throated critic. He often disagrees with his Father [William Jackson Hooker], who can be stuck in old ways of thinking, JDH stops him from publishing outdated views. They clashed over the JOURNAL [OF BOTANY] work, JDH is glad it is discontinued. JDH offers Gray species of Rubiaceae, he might bring them himself if he goes to the USA this year. Has consulted Huxley re. Gray's notes on vitality & offers his comments. Discusses his thoughts on dedoublement, at length, he has discussed the theory with [George] Bentham[GB] & does not consider it logical. Mentions Gray's work on Balanophoreae. Discusses in detail Dicotyledonous exogens & the hierarchy of flowering plants, enumerating the characteristics which should define the highest type. He thinks that the 'vegetable ladder' should be arranged by physiology of the reproductive organs with organic complexity secondary: this would elevate gymnosperms above Phaenogams. [Arthur] Henfrey has found the corpuscula[?] in Gnetum, he suspects the seeds take 7 years to ripen. JDH describes the development of Gnetum ovule during fertilisation. JDH is working on East India Company Assistant Surgeon competitive examination papers & Royal Society Report for [David] Livingstone's expedition. Comments that Gray has correctly described Sambucus fruit. Describes his observations on ovules in different plant genera & families: Viburnum, Caprifol[iaceae]. Conv[olvulaceae]. Aral[iaceae]. Umbelli[ferae]. Rubiaceae, with particular reference to raphe in Lonicerae. He suspects ovule structure will lead to affinities. He discusses his study of Chimonanthus, which he places nearer Monimiaceae & Annonads than Rosaceae, calycifloral characteristics being key. JDH thinks Cumming's Morinda is new. He is sending a fruit of Ceylon [Sri Lanka] Eupyrena. GB recommends his notes on Rubiaceae. Gray could send his notes on Timonius to the Linnean journal, JDH has not received the proof of Gray's Magnolia paper.
