To T. H. Farrer   10 April 1874

Down, | Beckenham, Kent.

Ap. 10 1874

My dear Farrer

I am delighted to hear about Coronilla. You must publish an account, & especially with diagrams.1 Pray attend whether the bee penetrates & ruptures with its proboscis the cells on the calyx, as I believe to be the case with the nectaries of Orchis mascula &c.2

I do not quite understand the claw on the vexellum, but I will shew your note to my son Frank.3

yours very sincerely | Ch. Darwin

Footnotes

See letter from T. H. Farrer, [before 10 April 1874] and n. 2. Farrer published a short paper on fertilisation in Coronilla (crown vetch) with two diagrams in Nature (Farrer 1874).
In Orchids, p. 15, CD had described the rupture of the rostellum by bees as they tried to get at the nectary in Orchis mascula (the early purple orchid).
