My dear Hooker

I do not remember sending any list, except one very long ago; but anyhow that does not signify.— The only seeds in pods (with some stalk) which I want are water or marsh plants, named. The widest rangers would be the most interesting to me, as Montia fontana & Callitriche verna.— We have no water here.— I have been trying some 60 or 70 pods, heads capsules &c to see about their floatation, & I sh^d. very much like to try some water plants, & likewise I sh^d like to try whether the vitality these same seeds can resist salt-water.—² I shall come to London on 15^th & stay till Saturday 18^th at noon.³

Supposing it proved convenient these seeds (& Vilmorins) c^d. be sent to 57 Queen Anne St,⁴ by that time per Deliverance Co^y.—or as soon after the 18^th, as you please as before requested.—

With many thanks | Ever yours | C. Darwin

I read long ago your Review on Decandolle with very great interest.⁵ He will be disgusted at your estimation of Botanical Geography; though I sh^d. think, pleased with all the first part.—
