Examining JDH’s list. CD struck by how many plants are common to Europe, S. America, and Australia.
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.
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.
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.
