To George Bentham 1 December [1857]
Summary
Thanks GB for his help on naturalised plants; comments on spreading of plants.
Wants to quote GB on the names of species and varieties of Silene on which C. F. von Gärtner experimented.
Thinks GB will be disappointed in his book [Natural selection]. "It will be grievously too hypothetical."

Thanks GB for his answers [to 2184], which were as explicit as he expected. Cucubalus viscosus and italicus are extremely sterile together; all other forms extremely fertile. Other instances of infertility found by Gärtner.
