 appearing with the leaves, leafy at base, cylindrical, the fertile elongating in 

 fruit; ovary lanceolate, tapering to the summit. — Var. ufciDA has the leaves 

 large and rigid, with coarser teeth, of which the lowest are somewhat elongated. 

 (S. rigida, Mu/d. S. Torrcyima, Barrati, which has leaves of a deeper green 

 beneath, appears to belong here.) — Var. mykicoidks has narrower leaves, 

 neither heart-shaped nor truncate at the base. (S. myricoidcs, J/uA/.) — Var. 

 anglstXta has lanceolate tapering finely serrate leaves, acute at the base, and 

 a more slender style. (S. angustata, Pi(rs/i, & Ed. 2.) — Low or inundated 

 places : common. — Shrub or small tree, with leaves 2i' - 6' long. 

 § 3. Catkins lateral, with a jew leafy bracts at the base, nppeuriuy with the leaves in 

 May or June : ovary stalked, silky-hnary ; stamens 2 : scales persistent, 



10. S. livida, Wahl., var. OCCidentalis. (Livid W.) Leaves oblong 

 or obovatc-lanccolate, acute, obscurely toothed, downy above, prominently veini/, 

 softly liairy and glaucous beneath; stipules semilunar, toothed ; catkins cylindrical, 

 the fertile becoming loose in fruit; ovary almost linear; style scarcely any; 

 pods slender, tapering from near the base, thtir very slender stalk longer than the nar- 

 row scale. (S. rostrata, Bichardson, & I"]d. 2. S. vagans, cincrascens, var. occi- 

 dentalis, Andt-rs.) — Moist or dry ground. New England to Penn., Illinois, and 

 northward : common. — Shrub 3° - 15° high. A transformation of the anthers 

 into imperfect ovaries is frequently observable in this species. 



11. S. chlorophylla, Anders. (Grekn W.) Glabrous, excerpt the cat- 

 kins ; leaves ohlung-laiiccolate or oblong, mostly entire, obtuse or acutish at 

 both ends (1'- 2' long), shining above, pale or glaucous beneath; fertile cat- 

 kins dense, short-cylindrical; ovary ovoid-conical; pod silky, very short-stalked ; 

 style slender; scale dark colored, villous. (S. phylicifolia, Ed. 2, not of Z.) —
