To C. J. F. Bunbury   [before 9 May 1856]

To C. J. F. Bunbury   21 April [1856]

Summary

CD writes on geographical distribution – "a grand game of chess with the world for a board".

Gives his hypothetical explanation why zoology of Cape [of Good Hope] is not so peculiar as its botany: it was once a group of islands – later united.

Tries hard to set forth the difficulties of his [species] theory.

Tells CJFB in confidence of his theory of the glacial epoch and its effect on plant distribution, such as identical species being found on summits of mountains in the tropics. Invites him to attack his "doctrine".

To C. J. F. Bunbury   9 May [1856]

Summary

On geographical dispersal of plants. Would be interested in CJFB’s views on representative species and on his hypothesis of a mundane cold period, which CD cannot prove geologically, but thinks, if it explains many facts of geographical distribution, may be admitted as probable. Hooker and Alphonse de Candolle do not agree with him.

From Charles James Fox Bunbury   7 February 1856

Summary

Has heard CD is much interested in questions relating to varieties and species. Mentions a case of a seminal variety of Colletia spinosa, described by John Lindley, which appears identical with another wild species of Colletia from S. America. Hopes CD will one day "enlighten us very much" on "the laws of species". There are many different views on the limits of species; M. F. Dunal made 50 species of Solanum which George Bentham considers are all varieties of S. nigrum.

Summary

Is interested by what CD tells him about his researches and speculations on species, variation, and distribution. Hopes he will not give up the idea of publishing his views. Advises CD on need for caution and candour. Raises some difficulties with "specific centre" theory of distribution.
