To T. H. Farrer   1 December [1873]

When you take up Coronilla, look to, as remotely analogous, fert. of Pedicularis in Annals & Mag. of Nat. Hist. December 1 1873. p. 497.1

C. Darwin

Down | Dec. 1st.


Thomas Meehan had described how the structure of the flowers of Pedicularis canadensis made self-fertilisation impossible in Meehan 1873; his paper was summarised in Annals and Magazine of Natural History 4th ser. 12 (1873): 497–8. In the Annals, Meehan’s observations were supplemented by those of Thomas George Gentry, who reported observing the flowers being visited by Bombus terrestris and described the process of pollen transfer (see also Gentry 1873). Farrer and CD had corresponded in August 1873 on the floral morphology of Coronilla (see, for example, letter to T. H. Farrer, 14 August 1873).


Gentry, Thomas George. 1873. [Report on fertilization of Pedicularis canadensis.] [Read 10 June 1873.] Proceedings of the Academy of Natural Sciences of Philadelphia 25: 287–90.

Meehan, Thomas. 1873. Fertilization of Pedicularis canadensis. [Read 3 June 1873.] Proceedings of the Academy of Natural Sciences of Philadelphia 25: 287.


Suggests a reference to Annals and Magazine of Natural History, 1 Dec 1873, p. 497, when THF takes up Coronilla.
