To Thomas Rivers 8 June 1
Down. | Bromley. | Kent. S.E.
My dear Sir
I thank you most cordially for the Cytisus, after examining which I forwarded to Prof. Caspary at Kœnigsberg;2 so you have killed two birds with one act of kindness. The C. adami case gets more & more perplexing. I wish your experiments with the buds of the Negundo had succeeded.—3 If you will not think me an insufferable bore, I wish you wd. observe whether Cytisus purpureus-elongatus produces any pods & inform me:—4
With many thanks | My dear Sir | Yours very sincerely | Ch. Darwin
Examined the Cytisus and forwarded to Caspary. The C. adami case "gets more and more perplexing", asks for report if Cytisus purpureus-elongatus produces any pods.
