Trees or shrubs, with watery juice, scaly bitter bark, soft usually light-colored wood, slender terete 
tough branches easily separable at the jomts, and fibrous often stoloniferous roots. 
Buds? sessile, 
appressed, acute or obtuse, covered by a single scale of two coats, the inner membranaceous, stipular 
and rarely separable from the outer, inclosing at its base two minute opposite lateral buds alternate with 
two small scale-like caducous opposite leaves coated with long pale or rufous hairs.’ 
folded in the bud, alternate except the first pair, simple, lanceolate, obovate, rotund or linear, entire, 
serrate or rarely dentate or subspinulose, their teeth often glandular, penniveined, petiolate with subterete 
Leaves variously 
short or elongated petioles, sometimes glandular at the apex and more or less covering the bud by their 
enlarged bases, turning yellow or falling with little change of color in the autumn, or persisting during 
the winter and leaving U-shaped or arcuate elevated leaf-scars displaying the ends of three small equi- 
distant fibro-vascular bundles. 
often persistent, generally large and conspicuous on vigorous young branches, leaving, when they fall, 
Flowers dicecious,* often fragrant, appearing before or with the unfolding of 
Stipules oblique, usually serrate, small and deciduous, or foliaceous and 
minute persistent scars. 
1 Salix does not form a terminal bud, the end of the branch 
dying during the summer or autumn, and leaving a minute scar 
close to the upper axillary bud, which prolongs the branch the fol- 
lowing season. (See Ohlert, Linnea, xi. 640 [Knosp. Baume und 
Strducher]). 
2 According to Henry (Nov. Act. Ces. Leop. xxii. 329, t. 31), who 
appears to have overlooked the fact that the bud-scale of Salix cor- 
data, Mueblenberg, separates readily into two coats, the bud-cover- 
ing of Salix consists of the union of two opposite connate leaves 
bearing in their axils the two rudimentary buds, while Lindley 
(Introduction to Botany, ed. 3, 144) considers that the minute oppo- 
site buds under the scale of the bud of Salix help to confirm his 
view that stipules were only modified leaves. 
8 Androgynous aments in Salix are not rare, and occasionally 
staminate and pistillate aments are found on the same plant. (See
