Dear Dyer

Will you ask D^r Hooker, or if he is not at home take the responsibility to send me two or three flowers of any Catasetum, should one flower during the next month or two, as I want very much to try one experiment on them.¹

I should further be much obliged for a raceme of Acropera, Acineta, or Gongora.² If a little damp moss were tied round their cut foot-stalks & they were sent me in a tin box by post, they would arrive in quite a fit state for my observations.

Forgive me for troubling you, & believe me | Yours sincerely | Ch. Darwin
