Darwin, Charles Robert
Darwin-Hooker Letters
<p style='text-align: justify;'>Has read first sheets of JDH’s <i>Flora Tasmaniae</i> [introductory] essay [published separately as <i>On the flora of Australia</i> (1859)]. Criticises lack of evidence supporting views that best marked varieties occur at edges of range of species and that species remain under cultivation for many generations and <i>suddenly</i> begin to vary.</p>
