My dear Dyer

In truth I was ashamed of myself, when I saw what trouble I had caused you.— All your information is of the greatest use to me, & I beg of you to thank cordially Prof. Oliver. Mr Baker & the others who have aided me.2 I can say that I have not asked for information about the plants, in any case, without having spent much time about them.

Cyclamen will be of no use with respect nutation & burying the capsules, but your facts & Mr. Benthams suggestion about the step in burying shall be worked in in a new Edit. of Forms of Flowers which I must soon prepare.3

The variability of the bloom in the Fern is quite new to me, but I had analogous cases & intended to use the argument about the apparent unimportance of the secretion.—4

I will write to Saporta, as Hooker wishes me to do, & will give your general verdict & send the African leaf.—5

Once again let me thank you very sincerely for all your very valuable information

Yours sincerely | Ch. Darwin
