Sep 25 /69

Dear Mr Darwin.

Many thanks for the pamphlet sent, & duly received—on additions to fertility of Orchids;1 & which has interested me much. I must apologize for not having returned a paper on Phyllotaxis. I cannot understand part of it at all; viz: about the “rectangle” & the letters to the fig I found are wrong in some places.2 Though the rest of the paper is interesting.

I beg to send you a copy of my Expression on same subject.3

Hoping you are in good health | believe me | yrs very truly | Geo Henslow

Ch Darwin Esq
