Has been working hard at Lythrum
and spontaneous movements of tendrils.
Defends Drosera as a "sagacious animal" but does not know whether he will ever publish on it.

To Alphonse de Candolle 4 August [1863]
Summary
Asks AdeC to observe two species of Lythrum to see whether they are dimorphic as stated by Vaucher. CD can find no trace of this in dried specimens he has examined; "if either species present any difference in length of pistil and stamens, it is most likely that three forms should be presented".
