50. BLACK WILLOW Salix nigra Marshall |
Black willow is the largest and most widely distributed of the native willows, although it is rare above an altitude of 2000 feet in the Adirondacks and in the pine barrens of Long Island. It prefers moist or wet soils along streams or lakes but is sometimes found on fresh, gravelly or sandy soils where it can get plenty of light. It is of little importance as a timber tree as it often divides into several crooked, medium-sized trunks close to the ground and the wood is soft and weak. It is used chiefly for boxes, excelsior, pulp, and also for artificial limbs because of its lightness. |
Bark - thick, rough
with wide ridges covered by thick scales, varies in color from light to dark brown. Twigs - slender, smooth, somewhat drooping, very brittle at the base, reddish brown in color; falling to the ground they may take root and grow.
