ft * Leaves remotely denticulate with projecting teeth ; stamens 2 'y capsule glabrous 



or silky. 



4. S. longifolia, Muhl. Leaves liuear-lanceolate, 2-4' long, tapering 

 at each end, nearly sessile, more or less silky when young, at length smooth 

 and green both sides; stipules small, lanceolate, deciduous; aments linear- 

 cyliudric, often clustered at the ends of the l)ranchlets ; capsule shortly pedi 

 celled ; stigmas large, sessile. — Found sparingly along the Atlantic coast from 

 Maine to the Potomac ; common westward. A shrub, rooting extensively in 

 alluvial deposits and forming dense clumps. This species is a peculiar Amer-

 pinnately lobed.

 at the tip ; starnens 2 (usually 1 in n. 19), with glabrous Jilaments (united and

ir* Large shrubs or small trees (8 ~ 15° high); leaves obovate or elliptic-lanceo- 

 late, 2-4' long, acute or acuminate, more or less obscurely and irregularly 

 serrate, thin becoming rigid, glaucous beneath ; fertile aments oblong-cylindric,

 base, closer, finer and becoming obsolete *^o\. ard the point ; stipules ^' long or 

 more, and sharply toothed, or small and nearly entire ; aments closely sessile, 

 thick, oblong-cylindrical , V long or more, appearing before the leaves in earliest 

 spring; scales dark re I or brown, bee ming black, copiously clothed with long 

 glossy hairs ' s' yle short but distinct. — Var. eriocephala, Anders. Aments

 Anders. Aments more locsely flowered, less silky ; capsules more thinly to- 

 mentose ; style longer ; stigma-lobes laciniate ; leaves narrower. (S. prinoides, 

 Pursh.) Includes narrow-leaved forms of the type, and others which are prob 

 ably hybrids with S. cordata. — Low meadows and river-banks, common. The 

 just expanding leaves are often overspread with evanescent ferruginous 

 hairs.
