Originally from Hascall's swamp, near Flint, Mich., where it was discovered by Daniel Clarke, M. D.,

 posed hybrids as quasi-species, after the manner of Andersson, Kerner and others, I very much wish that 

 this beautiful willow should be called S. Clarkei, to commemorate the name of a botanist who has done 

 more than any other to give an impetus to the study of hybrid willows in this country, M. S. Bebb,
