SALICACE^E. (WILLOW FAMILY.) 48f) 



coides, Darl., Fl. Cestr., 3 ed.), is a hybrid between this species and S. sericea, 

 having the leaves, even those of the most vigorous shoots, tapering and rather 

 acute at base, glaucous or glaucescent beneath and sparsely appressed-hairy ; 

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

 coming glabrate, shortly pedicelled ; twigs brittle at base. A hybrid with the 

 European S. incana (surprising on account of the rarity of the cultivated 

 parent) is found at Ithaca, N. Y. (Dudley). 



15. S. glaucophylla, Bebb. Leaves varying from ovate with a broadly 

 rounded base to oblong-lanceolate and equally pointed at both ends (3-4' lonej, 

 nearly 2' wide), glandular-serrate, subcoriaceous, glabrous throughout, dark green 

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

 shaped, dentate ; arnents thick, oblong-cylindrical, in size and silkiness resem- 

 bling n. 6; capsules attenuate-rostrate, 3-5' long, greenish, drying brown. 

 Var. ANGUSTIFOLIA, Bebb ; leaves narrower (3' long, f ' wide), pointed at both 

 ends. (S. angustata, of ed. 2, in part.) Var. BREVIF^LIA, 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. 111. 

 and Wise. 



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

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

 length rigid, dark green above, paler or glaucous and prominent/ y reticulate-veined 

 beneath, slightly glandular serrulate ; petioles long and slender ; stipules obso- 

 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, 1 823 ; rediscovered by Pringle, 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, with a long silky tomentum on both 

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



17. S. adenophylla, 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 leafy-peduncled, 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. 



-i- Low erect shrub, 1 -3 high; leaves small, entire ; capsules oblong-cylindric ; 



stigmas sessile or nearly so. 



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

 or somewhat pointed, entire, smooth on both sides, somewhat coriaceous when 

 mature, revolute, reticulated, pale or glaucous beneath ; fertile aments oblong, 

 loosely few-flowered, borne on long leafy peduncles ; capsules reddish green ; 

 pedicels slender, twice the length of the nearly smooth greenish yellow scale. 



Var. PEDICELL\RIS, Anders.; leaves oblong-linear or oblanceolate, 1-2V 

 long. Cold peat-bogs, N. Eug. and N. J. to Iowa, and northward. (En.)
