In this, his second article on the genetics of Fraxinus, the author stresses the divergent inheritance patterns found in the white and the red ash. These differences are all the more remarkable in view of the close relationship and morphological similarity between the two species. They indicate that an extension of the results of provenance studies on a few European softwoods cannot be relied upon to give an adequate genetic background for the exceedingly rich and varied forest flora of the United States. Instead, it will be necessary to investigate separately the inheritance of each of our important native tree species if genetics is to make the fullest possible contribution to forestry.
