DCP-LETT-1576

From:
Joseph Dalton Hooker
To:
Charles Robert Darwin
Date:
[29 June 1854]
Source of text:
DAR 205.9: 383
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.
