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
