Darwin-Hooker Letters
<p style='text-align: justify;'>Thanks for opinion on <i>Drosera</i>. After working for a time on a subject he is absolutely incapable of judging its value.</p><p style='text-align: justify;'>Has found a case in <i>Lythrum</i> of a necessary triple alliance between three hermaphrodites; the strangest case of propagation recorded among plants or animals.</p><p style='text-align: justify;'>Asks for <i>L. thymifolia</i> to see how a trimorphic form passes or graduates into dimorphic.</p><p style='text-align: justify;'>Questions JDH on <i>Linum perenne</i>.</p><p style='text-align: justify;'>Has found 33 hybrids in one field between <i>Verbascum thapsus</i> and <i>V. lychnitis</i>. The perfect series of varieties would have justified running the species together, but every one of the intermediate forms is sterile.</p>
