19211 SCHNEIDER, NOTES ON AMERICAN WILLOWS. XI 1D3 



S. lutea. Ball, in his MS.-list, is inclined to refer this form to a new 

 species of his of which I have not yet seen a specimen. 



Of S. monochroma I have been able to examine specimens from British 

 Columbia (Revelstoke) , Washington (Whitman, Colum})ia Counties), 

 Idaho (Nez Perces, Latah, Bannok Counties), Montana (Chouteau, 

 Gallatin, Lewis and Clark, Teton Counties), Wyoming (Yellowstone 

 Park), and Oregon (Crook, Umatilla, Union, Wallowa Counties). It is 

 probably a widely distributed species on the mountains of these states 

 and until now mostly mistaken for 5. cordata or the so called *S. pseudo- 

 myrsinites of authors.

 illifolia is the correct name 



to be applied to the forms of the British American and the Rocky Moun- 

 tain Willows passing as S. novae angliae or S. pscndomyrsinites. In 1858 

 Andersson described two American subspecies of S. myrsiiiitcs as S. 

 psendomyrsinitcs and S. curtijlora, and besides these two to which he gave 

 binomial names, although they were not intended by Andersson to be 

 egarded as species but as subspecies (later changed into varieties), he 

 proposed S. myrtillifolia as a good species. In his Monograph in 1867 

 (not 1865 as quoted by Fernald in 1914), Andersson "in his mature judg- 

 ment" (as Fernald said) considered these three shrubs as belonging to 

 one North American species, " for which he unfortunately proposed a new 

 name: S. Novae Angliae, and (in 1868 as varieties) he proposed "tres 

 formas habitu inter se baud parum diversas sed modiflcationibus numer- 

 osis indubie connexas," using the names S. pseudo-myrsinites, S. psendo- 

 cordata (instead of the older S. curtijlora of 1858) and S. myrtillifolia. 

 In 1868 (not 1864 as quoted by Fernald) in De CandoUe, Prodr. xvi.^ 

 fasc. II, Andersson went even a step farther in reducing the three sub- 

 species to varieties, and keeping the names used in 1867.
