Sends CD "L’applicazione della teoria Darwiniana ai fiori ed agli insetti visitatori dei fiori" [Bull. Soc. Entomol. Ital. 2 (1870)]. Continues to support vitalism and teleology.

Transformism explains rudimentary organs, and teratology, which are otherwise inexplicable.

Looking forward to publication of Descent

and CD’s expected book on "Variation in nature" [see Variation 1: 4].

Responds to CD’s request for Canna seeds.

Studying dichogamy in Lotus. Describes mechanism that pumps pollen on to a visiting bee. Corrects Axell on Lotus.

Thanks FD for seeds of Canna.

Still thinks it would be worth FD’s while looking at the fertilisation of Lotus; does not think Frank Darwin has exaggerated the novelty of the contrivance.
