SALICACEAE 57 



reddish to purple, finely hairy on the lower half, and about 

 l/s inch long. 



Catkins appear at about the same time as the leaves. They 

 stand on short, leafy pedicels, especially the pistillate ones, which 

 are ^ to \l4 inches long and erect in fruit. The catkin scales 

 are light brown, obovate, and thinly to densely fine-hairy. The 

 styles of the pistillate flowers are short, spreading, and divided, 

 with 2 long, spreading stigmas. The capsules at maturity are 

 lanceolate, at first finely hairy but at maturity nearly glabrous, 

 and stand on pedicels about one-sixteenth inch high. 



Distribution. — This unusual willow is known in Illinois 

 only through collections of E. J. Hill at West Pullman, Cook 

 County, and from the Barrens near Kankakee. 



SALIX CANDIDA Fluegge 

 Sage Willow Hoary Willow 



The Sage Willow, fig. 7, is a low, very branchy shrub generally 

 ^ to 10 inches, rarely 3 feet, high, with long, narrow, densely 

 white-tomentose leaves. The leaf blades are linear-oblong or 

 narrowly oblanceolate, ^ to 14 i"ch wide by \]/i to 4 inches 

 long, and acute at the apex and at the base. They have revolute, 

 conspicuously glandular margins that usually are entire but 

 occasionally are crenulate. They are dark green and dull, nearly 

 glabrous to thinly tomentose, with sunken veins above, and 

 densely white-tomentose beneath. The petioles, about l/g to 

 14 inch long, are more or less whitened with tomentum. The 

 moderately slender, round branches are divaricate, at first 

 white with dense tomentum, later glabrous and yellowish, red 

 brown or even darker, with buds spaced \4, to \^ inch apart, 

 and often marked by distinct, fine ridges which are decurrent 

 from the leaf-scars. The buds are red brown to red, ovate, 

 blunt and rounded, often flattened, rather closely appressed, 

 glabrous to tomentulose, and one-sixteenth to ]/% inch long. 



Catkins appear at about the same time as the leaves and 

 are nearly sessile, or the pistillate ones may have leafy bracts 

 and peduncles. They are ^/i to II/2 inches long in flower, and 

 the pistillate catkins become ^ to 2 inches long in fruit. Scales 

 are brown, obovate, and thinly hairy. Staminate flowers bear 

 2 stamens with slender, glabrous filaments; and the styles of 

 pistillate flowers are short, reddish, entire or divided, and
