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 leaves, 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,
