From J. D. Hooker [29 June 1854]
Summary
JDH on "highness" of Coniferae: they are genuine Dicotyledons, not a link to cryptogams; that is a geologists’ fallacy. Thus they are highest plants in Carboniferous.
Does not agree with CD’s "elastic" species theory. Long correspondence with Lyell on this.

From J. D. Hooker [15 November 1854]
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.

From J. D. Hooker 5 December [1854]
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.
Difficulty of distinguishing affinity and analogy in plants.
