Asks GB to support the election of CD’s nephew, Henry Parker, to the Athenaeum Club.

Thanks GB for his "Report on [the recent progress and present state of] systematic botany" [Rep. BAAS (1874): 27–54] and for the way in which he refers to CD’s book.

Asks GB to send him flowers of the two forms of Boronia pinnata, as he is republishing his papers on dimorphic plants [Forms of flowers].

Sends copy of Cross and self-fertilisation.

Sends specimens of Boronia.

Discusses the section on diclinous trees and herbs in CD’s new book [Cross and self-fertilisation, pp. 411–13]. CD’s theory that diclinism preceded hermaphroditism seems confirmed.

Has examined the specimens of Boronia pinnata. No evidence of two distinct bodies of individuals.

Asks whether extra-American species of Aegiphila are heterostyled.

Believes Aegiphila to be exclusively American.

Contrasts fertilisation of Australian Acacia with Brazilian Mimosa.

Thanks CD for Forms of flowers. Comments on the chapter on cleistogamic flowers; offers some corrections.

Thanks GB for corrections to chapter on cleistogamic flowers [Forms of flowers].

Asks for his opinion on "bloom"-producing plants in different climates.

Answers CD’s query on "bloom".

CD’s election to the French Academy delights GB. Nationalistic prejudices have at last been overcome; congratulates him on what is now universal adoption of his views.

GB’s note has given him more pleasure than his election to the French Academy.
