Abstract
DURING recent cytological investigations in the Salicaceæ, undertaken to demonstrate the presence or absence of sex- or heterochromosomes in certain species of Salix, I have discovered such chromosomes in the males of Salix lucida Muhl., S. aurita L., S. cinerea L., and S. Andersoniana Sm. Of these species, S. lucida, an American form, belongs to the section Pentandræ of the supersection Pleiandræ, S. aurita and S. cinerea to the Capreæ group of the Diandræ, and S. Andersoniana to the Phylicifoliæ of the same supersection; all are, of course, di"cious. Of the polyploid series developed in Salix, S. lucida, S. aurita and S. cinerea are tetraploids, and S. Andersoniana hexaploid.
