This is one of two very common shrubby willows found beside mountain streams at 

 middle elevations almost throughout the State. Rarely it takes the form of a low 

 tree, but it is usually a shrub 3 to 4 meters high or less. The catkins appear before 

 the leaves, from rather large buds borne on glaucous stems, and are closely followed 

 by short, narrowly elliptic-oblong lea\'es, 2 or 3 cm. long. The summer foliage con- 

 sists of numerous, thin, narrowly oblong-lanceolate, abruptly acute, entire or serrate 

 leaves 15 cm. long or less, dark green above and very glaucous beneath. The stems 

 may retain their glaucous coat, but are usually brown.
