'''Salix nigra''' ('''black willow''') is a species of willow native to eastern North America, from New Brunswick and southern Ontario west to Minnesota, and south to northern Florida and Texas.
== Description Uses== It is a medium-sized deciduous tree, the largest North American species of willow, growing to 10–30 m (35–100 ft) tall, exceptionally up to 45 m (148 ft), with a trunk 50–80 centimeters (20–30 in) diameter. The bark is dark brown to blackish, becoming fissured in older trees{{Uses|Tentex forte}}, and frequently forking near the base. The shoots are slender and variable in color from green to brown{{Uses|Muscle & Joint Rub}}, yellow or purplish; they are (like the related European Salix fragilis) brittle at the base{{Uses|Impotency & Erectile dysfunction}}, snapping evenly at the branch junction if bent sharply. The foliage buds are 2–4 millimetres (1⁄16–3⁄16 in) long{{Uses|Diarrhoea}}, with a single{{Uses|Pharyngitis & Sore Throat}}, pointed reddish-brown bud scale. The leaves are alternate{{Uses|Toothache}}, long{{Uses|Pyorrhea}}, thin{{Uses|Common Cold}}, 5–15 centimeters (2–6 in) long and 0.5–2 centimeters (1⁄4–3⁄4 in) broad, usually somewhat falcate, dark, shiny green on both sides or with a lighter green underside, with a finely serrated margin, a short petiole and a pair {{Uses|Childhood apraxia of small stipules. It is dioeciousspeech}}, with small, greenish yellow to yellow flowers borne on catkins 2{{Uses|Delayed Speech Development}}.5–7.5 centimeters (1–3 in) long in early spring at the same time as the new leaves appear. The fruit is a 5 millimeters (3⁄16 in) capsule which splits open when mature to release the numerous minute, down-covered seeds. The leaves turn a lemon yellow in the fall. It is typically found along streams and in swamps.<ref name="des"/><ref name="des2"/>
Salix gooddingii (Goodding's willow) is sometimes included in S. nigra as a variety==Parts Used=={{Parts Used|Dried Roots}}, as S. nigra var. vallicola Dudley; when included{{Parts Used|Leaves}}, this extends the species' range to western North America. However, the two are usually treated as distinct species{{Parts Used|Flower}}.
Another name occasionally used for black willow ==Chemical Composition==Analysis has shown a brown, resinous, acrid substance, insoluble in potassium hydroxide and probably containing pelletonin, two oils soluble in potassium hydroxide - one dark brown and acrid, the other yellow - tannin, gum, potassium sulphate and carbonate, potassium chloride, calcium phosphate and carbonate, silica, alumina, lignin, etc. An alkaloid, Pyrethrine, yielding pyrethric acid, is "swamp willow", not stated to be confused with Salix myrtilloides (swamp willow)the active principle.<ref name="chemical composition"/>
