Nov. 23. 1861

To Mr. Darwin

Sir

Having mentioned to Dr. Hooker a few notes which I had made upon the fertilization of the Victoria regia in these Gardens this Summer,1 he expresed a wish to send you word concerning it, but I fear notes so brief will be of little service to you, though from them I am led to believe that for the production of great quantities of seeds the Stigma must be impregnated with foreign pollen. 1st I noticed flowers left to impregnate themselves and they produced from 20 to 30 seeds in each Capsule, those flowers which I fertilized with their own pollen produced from 60 to 80 seeds in each Capsule, but one flower which was fertilized with the pollen of another flower though upon the same Plant, produced the immense number of 251 seeds quite perfect, but I cannot say if there would have been any perceptible difference in the Plants from these seeds and I shall not be able to come to any conclusion as they have unfortunately been mixed

I remain Sir Most | respectfully | Wm. Hugh Gower
