644. S. luclda. 



banks of streams, Nfd. to Man., s. to Pa., 111., and Neb. Fig. 

 644. Var, angustif6lia Anders. Leaves glabrous, elongate- 

 lanceolate, 1-1.5 cm. broad. — Nfd. and e. Can. 



Var. int6nsa Fernald. Branchlets of the first year and under 

 surfaces of the elliptic-lanceolate attenuate-based leaves per- 

 manently puhescent with sordid or rufous hairs. — Que., N. B., 

 and n. and w. N. E. 



^ ++ Leaves pale or white heneath ; fruit 

 mature in autumn. 



6. S. serissima (Bailey) Fernald. (Au- 

 tumn W.) Leaves elliptic-lanceolate or ob- 

 long-lanceolate, short-acuminate, in maturity 

 coriaceous, 4-8 cm. long, 1-8 cm. broad, closely 

 serrulate; staminate aments 1-1.5 cm. long, 

 1-1.2 cm. thick ; the fertile becoming loosely 

 flowered, 2-3.5 cm. long ; the olive- or brown- 

 tinged finally lustrous indurated capsule conic- 

 subulate, 7-10 mm. long, the pedicel twice 

 exceeding the gland ; tall shrub. — Mossy 

 swamps, mostly in calcareous regions, e. Que. 

 to Alb., s. to w. Ct., n. N. J., w. N. Y., and 

 the Great Lakes. Fig. 645.

-)- Leaves lanceolate or ovate-lanceolate, long-acuminate, closely serrate. 



7. S. FRAGiLis L. (Crack W.) I^eaves glabrous from the first, green both 

 sides, or only slightly paler beneath, in maturity 1-1.5 dm. long, 2.5-4 cm. broad^ 

 rather coarsely undulate-serrate, with about 5 (4-7) teeth 

 to each cm. of the margin ; stipules when present half- 

 cordate ; aments slender ; the staminate 

 3-5 cm. long ; the fertile becoming 5-7 

 cm. long ; capsule subulate-conical, 5 mm. 

 long, short-pediceled. — A large tree, early 

 planted, and now established. Que, to Ky. 

 — Freely hybridizing with S. alba. (Nat. 

 from Eu.) Fig. 646. 



8. S. ALBA L. (White W.) Leaves 

 pale icith silky pubescence on both sides, 

 in maturity 5-12 cm. lonr, 1-3 cm. broad, 

 finely serrulate, with about 9 (6-12) teeth 

 to each cm. of margin ; stipules ovate- 

 lanceolate, deciduous ; capsule ovoid-coni- 

 cal, 3-5 mm. long, sessile or nearly so. — 

 The typical tree, with greenish branch- 

 lets and leaves permanently silky, is sometimes planted and 

 rarely established in Am. Fig. 647. Var. vi- 

 TELLiNA (L.) Koch, with yellow or reddish 

 branchlets and the old leaves glabrous, white 

 beneath, is a familiar large tree of rapid growth, 

 commonly planted and freely spreading. Var. 

 CAERtJLEA (Sm.) Koch is similar, but with 

 olive-green branchlets and bluish-green leaves. — Hybridizes with 

 S. fragilis, S. lucida, etc. (Nat. from Eu.) 



9. S. BABYLONiCA L. (Weeping W.) Lcttves at first silky, 

 quickly glabrate, pale beneath, in maturity 6-12 cm. long, 0.5-1.5 cm. 

 broad, very slender-attenuate, sharply toothed ; aments 1.5-2 cm. long ; 

 the sessile plump capsules 1-1.5 mm. long. — Planted for ornament, 

 and locally spread along river-banks and lake-shores, particularly 

 from Ct. westw. and southw. (Nat. from Eu.) Fig. 648.
