capped by short, spreading, notched stigmas. The mature cap- 

 sules are about 14 inch long, lanceolate, and whitened with 

 tomentum. They stand on short pedicels that hardly exceed 

 the height of the floral glands. 



Distribution. — The Sage Willow is a shrub of the far north. 

 It ranges from Newfoundland and Labrador westward across 

 subarctic North America to British Columbia and southward 

 into the New England states, New Jersey, northern Ohio and 

 Indiana, and thence westward to the Rocky Mountains, where 

 it again ranges southward as far as Colorado. Throughout this 

 region it is an inhabitant of cold bogs in glaciated regions. In 

 Illinois, it occurs most abundantly in the tamarack and sphag- 

 num, bogs of Lake County and in lake shore and dune bogs 

 near Lake Michigan. It may, however, be found rarely in other 

 parts of the state, as is evidenced by collections made years ago 

 by Dr. Frederick Brendel in Tazewell County. The Tazewell 

 County records are southern points for the Sage Willow.

Goat Willow Sallow Willow 



The Goat Willow, fig. 7, a native of Eurasia, introduced into 

 America as an ornamental, is widely cultivated in Europe. It 

 is often a small tree or, with us, a treelike shrub with large, 

 coarsely subdentate leaves and moderately slender to large 

 branchlets. The leaves, which are 3 to 6 inches long, vary in 

 shape from narrowly ovate to rather broadly oblong-orbicular. 

 They are dark green and glabrous and marked by conspicuous 

 yellowish to brown midveins and w^hitish, prominent or obscure 

 veinlets above, whitish or grey tomentose beneath with promi- 

 nent, netted, brown veins and veinlets. The apex of the blade 

 is acute or abruptly pointed and the base is rounded to the 

 petiole, or subcordate, and the margins are revolute, subdentate 

 to crenulate, and without glands. The leaves stand on stout 

 petioles ^ to ^ inch long, which are more or less pubescent 

 to tomentose and glandless. The terete twigs are moderate to 

 coarse, tomentose when young but glabrate in age, and bear 

 bark that is somewhat wrinkled to smooth, yellowish brown 

 to dark red. The rather large, subconical buds are red to red 

 brown, somewhat appressed, Y% to ]/\ inch long, and either 

 puberulent or glabrate. The early deciduous stipules are sub-
