To Fritz Müller 3 April 
Down. | Bromley. | Kent. S.E.
My dear Sir
I have been staying for a month in London, & am at present, on my return home, somewhat overwhelmed with correspondents, so that I write merely to thank you for yr letter of Jan 29. (which, as usual, abounds with most curious facts) & to enclose seeds from crossed flowers of the Eschhotzia Californica.1 I am very much obliged for yr seeds (which however appear to be rather injured by pressure) which shall be sown, & I shall be very curious to hear how my enclosed seeds behave with you.2 Your diagram of the movements of the flower-peduncle of the Alisma is extremely curious: I suppose the movement is of no service to the plant, but shews how easily the species might be converted into a climber.3 Does it bend through irritability when rubbed? If you can prove alternate generation with neuter ants you will indeed make a remarkable discovery.4 I shall be very anxious to hear whether Pontederia turns out trimorphic.5 None of the plants which I have raised from yr seeds have as yet flowered so that I cd experiment on them.6 I have never examined the flowers of any Maranta; but the whole vegetable kingdom seems to abound with beautiful contrivances for crossing.7
Before this letter reaches you I hope that you will have recd my new book, which on the whole has been received well in England. At some distant day I shall be intensely curious to hear what you think of the hypothesis of Pangenesis; but I shall not be at all surprized if you disapprove.8
Your next letter will I hope tell me what you think of my plan of getting a translation of your book published.9
With very sincere thanks believe me yours very truly | Ch. Darwin
Movement in plants.
Would welcome FM’s opinion of Pangenesis.
