1918] SCHNEIDER—SALIX 21 
I am not sure whether this variety can be regarded as more than a mere 
form of S. Bonplandiana, but judging by the rather insufficient material before 
me I think it best to keep it as a variety, to which probably the specimen from 
southwestern New Mexico, enumerated under the type, should be referred. 
There is a specimen collected by E. Palmer in the state of Durango, at Tepe- 
_ huanes, March 25—April 16, 1906 (no. 9, m.; M., W.) which looks like a pubes- 
cent form of var. Toumeyi corresponding with the var. pallida of the type. 
7. S. LAEVIGATA Bebb in Amer. Nat. 8:202. 1874; in Watson, 
Bot. Calif. 2:83. 1879; Ball in Trans. Acad. Sci. St. Louis 9:69. 
1899. 
I mention this willow only because its occurrence might be expected in 
northern Lower California, but I have not yet met with a specimen of it from 
this region. As I have explained, the Guatemalan willow referred by BEBB 
to S. laevigata belongs to S. Bonplandiana. S. laevigata is the western counter- 
part of the eastern S. longipes.
