19 iq] SCHNEIDER— AMERICAN WILLOWS 331 



In Nevada and Utah a form is found in which the female 

 flowers have a ventral and a dorsal gland. To this form belongs S. 

 nevadensis Wats., the type of which came from Nevada, Ormsby 

 County, near Carson City. It is certainly not a good species, but 

 I am inclined to keep it as a variety until it is proved by further 

 observation that the presence of a dorsal gland is a character of no 

 taxonomic value, and that no other character can be detected by 

 studying the plant in the field. In proposing the name S. exigua 

 var. nevadensis, nov. var. (5. nevadensis Watson in Am. Nat. 

 7 1302. 1873), I provisionally refer to it the following specimens, and 

 wish to draw the attention of collectors to the localities mentioned. 

 The type has glabrous ovaries, with a pedicel nearly as long as the 

 ventral gland, while other forms with two glands have a more or 

 less dense pubescence.
