From:
Joseph Dalton Hooker
To:
Charles Robert Darwin
Date:
[15 Nov 1854]
Source of text:
DAR 205.9: 386
Summary:

George Bentham’s list of aberrant plant genera. JDH appended the number of species in each genus according to E. G. Steudel’s catalogue [Nomenclator botanicus (1840–1)] and according to JDH and Bentham.

JDH speculates on effect of splitting Australia longitudinally on distribution; it becomes an argument for new creations.

Source of text:
DAR 205.9: 388–90
Summary:

Bentham’s list of aberrant genera: CD’s worry that he eliminated large genera a priori is half right. He eliminated those large, anomalous genera that virtually constitute natural orders. JDH criticises CD’s tabulations of aberrants.
