Lyell receives Copley Medal; CD to write notes for JDH’s éloge of Lyell.
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.
Hermaphrodite trees are enough to "knock" CD down. Can JDH observe Eucalyptus to see whether pollen and stigma mature at same time?
JDH’s facts showing European plants are more common in southern Australia than in South America are disturbing because they are improbable on CD’s views of migration.
JDH said he would give examples of Australian forms that have migrated north along the mountains of the Malay Archipelago.
An enclosure sent with the letter to JDH, 14 November [1858] (Correspondence vol. 7) - questions and comments on lists of European species found in south-west Australia and Tasmania, and European genera found in Australia.
At work on the introductory essay to Flora Tasmaniae.
Discusses the effects of climate and geography on "vegetable strife".
CD declines to write Lyell éloge [for Copley Medal] because of his ill health.
Praises JDH’s Australian introduction.
Disputes JDH’s emphasis on SE. and SW. Australian flora.
Memorial concerning British Museum collection.
Relation of Cape of Good Hope and Australian flora a great trouble. CD’s high estimation of importance of glacial period for distribution.
Examining JDH’s list. CD struck by how many plants are common to Europe, S. America, and Australia.
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.
Wide-ranging species more "improved" than relics in small areas because they exist in large numbers and thus are subject to intense competition.
His abstract is 330 folio pages long so far.
JDH cannot abide CD’s connection of wide-ranging species and "highness". Australian flora contradicts this in many ways.
Replies at length to JDH’s worried reaction to his comments on lowness of Australian plants. CD distinguishes between "competitive highness", i.e., which fauna would be exterminated and which survive if two faunas were placed in competition, and ordinary "highness" of classification.
