Summary:
He has finished MEW’s work on hybrid willows [Die Bastardbefruchtung im Planzenreich (1865)] and sends his thanks. The extreme frequency of hybrid willows is new to CD, and he finds the explanation of their numbers in certain locations ingenious.
Comments on the criticism of Gärtner’s view of reversion
and the differences between MEW and Naudin.
CD now has doubts regarding his own view that hybrids are sterile from not being perfectly accommodated to their conditions of life.
