'''''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]].<ref name=grin>Germplasm Resources Information Network: [http://www.ars-grin.gov/cgi-bin/npgs/html/taxon.pl?102718 ''Salix nigra'']</ref> [[File:Salix nigra catkins 8001.JPG|thumb|left|200px|Flowers]]It is a medium-sized [[deciduous]] [[tree]], the largest North American species of willow, growing to 10-30 m tall, exceptionally up to 45 m, with a trunk 50–80 cm diameter. The [[bark]] is dark brown to blackish, becoming fissured in older trees. The shoots are slender, variable in color from green to brown, yellow or purplish; they are (like the related European ''[[Salix fragilis]]'') brittle at the base, snapping evenly at the branch junction if bent sharply. The foliage buds are small, 2–4 mm long, with a single pointed reddish-brown bud scale. The [[leaf|leaves]] are alternate, long, thin, 5-15 cm long and 0.5-2 cm broad, usually somewhat [[leaf shape|falcate]], dark, shiny green on both sides or with a lighter green underside, with a finely serrated margin, a short [[petiole (botany)|petiole]] and a pair of small [[stipule]]s. It is [[Plant sexuality|dioecious]], with small, greenish yellow to yellow [[flower]]s borne on [[catkin]]s 2.5-7.5 cm long in early spring at the same time as the new leaves appear. The [[fruit]] is a 5 mm [[capsule (fruit)|capsule]] which splits open when mature to release the numerous minute, down-covered [[seed]]s. It is typically found along streams and in swamps.<ref name=borealforest>Tree Species of the World's Boreal Forests: [http://www.borealforest.org/world/trees/black_willow.htm ''Salix nigra'']</ref><ref name=ncp>Trees of the North Carolina Piedmont: [http://www.ibiblio.org/openkey/intkey/web/SANI.htm ''Salix nigra'']</ref><ref name=nb>New Brunswick tree and shrub species of concern: [http://cfs.nrcan.gc.ca/subsite/mx-212/blackwillow ''Salix nigra'']</ref> ''[[Salix gooddingii]]'' (Goodding's Willow) is sometimes included in ''S. nigra'' as a [[variety (botany)|variety]], as ''S. nigra'' var. ''vallicola'' Dudley; when included, this extends the species' range to western North America.
