482 SALICACE.E. (WILLOW FAMILY.) 



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



or silky. 



4. S. longifolia, Mulil. Leaves linear-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- 

 cylindric, often clustered at the ends of the branchlets ; 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- 

 ican type, and exceedingly variable ; the earliest leaves after germination 

 piunately lobed. 



2. Aments lateral or terminal, with or without bracts ; scales persistent, colored 

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

 hairy in S. purpurea) ; shrubs or small trees. 



* Capsules tomentose. 



-i- Pedicels 3-6 times the length of the gland ; style medium or none. 

 M- 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, 

 2 3' long, loosely flowered. 



5. S. rostrata, Richardson. Leaves dull green and doicny above, stoutly 

 veined and soft-hairy beneath, serrate, crenate or subentire; stipules when pres- 

 ent semi-cordate, toothed, acute ; aments appearing with the leaves, the sterile 

 narrowed at base, pnle yellow; capsules tapering to a very long slender beak; 

 pedicels thread-like, much exceeding the pale, rose-tipped, linear, thinly vi/lous 

 scales ; style scarcely any ; stigma-lobes entire or deeply parted. (S. livida, 

 var. occidentalis, (Jnt//.) Moist or dry ground, N. Eng. to Penn., and far 

 west and northward. N^t spreading from the root but having rather the habit 

 of a small tree, with a distinct trunk. 



6. S. discolor, Muhl. (GLArcous W.) Leaves smooth and bright green 

 above, soon smooth be> t e (th, irregularly crenate-serrate, the serratures remote at 

 base, closer, liner and becoming obsolete toward the point ; stipules \' long or 

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

 thick, oblong-cylindrical, 1' long or more, appearing before the leaves in earliest 

 spring; scales dark red or brown, becoming black, copiously clothed with long 

 gloxsy hairs ; style short but distinct. Var. EKIOCEPIIALA, Anders. Aments 

 more densely flowered and more silvery silky ; leaves sometimes retaining a 

 ferruginous pubescence beneath even when fully grown. Var. PRINOIDES, 

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

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

 Pnrsh.) 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. 



-w- -M- Upland grayish shrubs, 1-8 high ; leaves oblanceolate , pointed, the low- 

 est obtuse, doini'i above becoming glabrate, beneath glaucous, rugose-veined 

 and softly tomentose, the margin revolute, undu/ate-entire; aments ovoid or
