To George Henslow 15 [June 1866]
Summary
CD believes most strongly in reversion. J. G. Kölreuter’s, K. F. v Gärtner’s, and some of Charles Naudin’s cases leave no doubt in his mind. Forgets whether Herbert gave cases but in conversation he certainly believed in it. Thinks Gärtner is right to say reversion occurs only rarely in plant hybrids which have not been cultivated.
