 stipules small, ovate, pointed; capsules more or less silky when young, be-

 and shining above, glaucous beneath, the young drying black ; stipules large, ear- 

 shaped, dentate ; aments thick, oblong<'ylindrical,'\n size and silkiness resem-

 ends. (S. angustata, of ed. 2, in part.) — Var. ijrevif6lia, Bebb; leaves 

 obovate, about 1' long, strongly veined. — Common on the sand dunes of 

 Lake Michigan, and occasionally found away from the lake shore in N. Ill 

 and Wise. 



16. S. balsamifera, Barratt. Leaves broadly rounded and usually sub- 

 cordate at base, at jirst very thin, subpeliucid and of a rich reddish color, at

 lete ; fertile aments becoming very lax in fruit, the long slender pedicels 6-8 

 times the length of the gland ; style short. (S. pyrifolia, Anders.) — In open 

 swamps along our northern boundary, Maine to Minn., and northward; White 

 Mountains of N. H. {Little, 1823; rediscovered by Pr ingle, and C. E. and E. 

 Faxon). A much branched shrub, growing in clumps; recent twigs shining- 

 chestnut on the sunny side. 



•M. ++ Leaves clothed, even when fully grown, icith a long silky tomentum on both 

 sides, ivhich is finally deciduous; capsule subsessile ; style elongated. 



17. S. adenoph^lla, Hook. Leaves ovate or very broadly lanceolate, 



cuspidate-acuminate (1-2' long), dull green both sides, very closely serrate 

 with fine projecting gland-tipped teeth ; stipules conspicuous, ovate-cordate, 

 glandular-serrate, exceeding the short stout petioles, which are dilated at base 

 and embrace the obtuse silky buds; aments Icafy-pedunded, the fertile not 

 rarely becoming 4' long, densely flowered. — Shores of the Great Lakes, root- 

 ing extensively in the sand-dunes. A large straggling shrub, with stout to- 

 mentose twigs and crowded leaves. Hybridizes with S. cordata. 



•^ -t- Loiv erect shrub, I -3° high ; leaves small, entire ; capsules oblong-ry I indric ; 

 stigmas sessile or nearly so. 



18. S. myrtilloides, L. Leaves elliptic-obovato, about 1' long, obtuse
