Continued debate on formation of species as a result of retreat from glaciers.

From J. D. Hooker 7 December 1856
Summary
Has done New Zealand flora calculations. Results support CD’s theory of necessity of crossing. Trees tend to have separate sexes.

From J. D. Hooker [24 March 1863]
Summary
Has been looking at separation of sexes in poplars.
Interested in reversion.
Does not understand all CD said on inheritance.
JDH now remembers that Origin was "published" some time before it was "distributed" and therefore appeared prior to his own essay [see also 2478].
Impossible to say whether some Dipterocarpaceae survived a cold period or have developed since.

From J. D. Hooker [11 April 1857]
Summary
JDH cites W. H. Harvey’s observations on Fucus and David Don’s on Juncus as examples of variations that are independent of climate. There are many such cases. Gives his working scheme for categorising variation.

From J. D. Hooker [2 December 1857]
Summary
News of Mrs Henslow’s death.
Studying Impatiens, which bears on CD’s problems. Though genus is endemic to India, with over 100 species, CD will be glad to know they do not run into one another.

From J. D. Hooker [6 December 1857]
Summary
Finds CD’s results [of his survey of well-marked varieties from A. P. and Alphonse de Candolle’s Prodromus systematis naturalis regni vegetabilis (1824–73)] "very curious and suggestive". Thinks the Labiatae will present an obstacle to him as it is a very large and distinct order with well-defined species and genera. Would like to see him tackle more volumes of Candolle’s Prodromus, as his case can only be established by evidence from mundane plants. CD should beware of generalising from local species variability. A comparison of C. C. Babington’s and G. Bentham’s [British] Floras [Babington Manual of British botany (1843, 4th ed., 1856); Bentham Handbook of British flora (1858)] would be invaluable. Suggests CD write to Ferdinand Müller and Charles Moore in Australia. Moisture favouring extension of species is important for CD’s view.

Summary
Sending more Candolle volumes for survey of species with well-marked varieties.
Has begun his introduction [to Flora Tasmaniae]; will not make generalisations.
J. D. Dana’s pamphlet too metaphysical for JDH.

From J. D. Hooker [25] February 1858
Summary
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.

From J. D. Hooker 13–15 July 1858
Summary
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.

From J. D. Hooker 22 December 1858
Summary
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.

From J. D. Hooker [26 December 1858]
Summary
JDH cannot abide CD’s connection of wide-ranging species and "highness". Australian flora contradicts this in many ways.
