An erect slender glabrous shrub, i°-3° high, the 

 twigs light brown, terete. Leaves linear-oblong, 

 elliptic-oblanceolate or obovate, obtuse or acute at 

 the apex, entire, mostly narrowed at the base, i'-3' 

 long, 3"-8" wide, short-petioled, bright green above, 

 pale or glaucous beneath, their margins slightly 

 revolute; aments expanding with the leaves, leafy at 

 the base, rather dense, 1' or less long, or the pistil- 

 late longer in fruit ; bracts persistent, obtuse, slightly 

 villous ; stamens 2 ; filaments glabrous ; style shorter 

 than or equalling the stigmas; gland short; capsule 

 oblong-conic, obtuse, glabrous, 2V long, 2-3 times 

 as long as the filiform pedicel which slightly exceeds 

 the scale. 



In bogs, New Brunswick and Quebec to British Colum- 

 bia, New Jersey, Pennsylvania, Ohio and Iowa. April- 

 May. Has been confused with the similar S. myrtil- 

 loides L., of Europe. 



Salix fuscescens Anders., occurring on Mt. Albert, 

 Quebec, in Alaska, and in western Siberia, differs in a 

 longer-pointed gland, the capsule glabrous or loosely pubescent.

 green, subtruncate, about ii" long; filaments gla- 

 brous ; capsule conic, glabrous, very short-pedicelled, 

 2" long ; style slender, twice as long as the stigmas. 



On rocks and in alpine meadows, Mount Albert, 

 Quebec. 



Salix calcicola Fernald & Wiegand, another recently 

 described boreal species with glabrous capsules and long 

 styles, has large terminal and lateral catkins and nearly 

 orbicular leaves ; pale beneath.

Salix reticulata L. Sp. PI. 1018. 1753. 



Salix orbicularis Anders, in DC. Prodr. i6 2 : 300. 1868. 



A procumbent shrub, 3'-io' high, often sending

 tuse, narrowed, rounded or subcordate at the base, 

 slender-petioled, glabrous or somewhat silky-pubes-

 glaucous and strongly reticulate-veined beneath, 1 - 

 2' long; petioles 4' -12" long, channeled, not glan- 

 dular; leaves obscurely crenulate or entire; stipules 

 oblong, obtuse; aments terminal, long-stalked, dense; 

 bracts obtuse; stamens 2; filaments distinct, pubes- 

 cent at the base; stigmas' sessile; capsule ovoid- 

 conic, sessile, tomentose, about 3" long.
