90 BLACK WILLOW. Salix nigra, Marshall. FORM—Largest of our native tree-willows, usually 25-30 ft. high with a diameter of 10-20 Inches, but may reach a height of 60-80 ft., with a diameter of 2-3 feet. Trunks usually crooked, often inclined and occurring in small groups. Crown wide, open and round-topped. BARK—Thick, rough, deeply furrowed, blackish-brown, with wide ridges covered with thick scales. Ridges of bark often connected by narrow, transverse or diagonal ridges. TWIGS—Slender, smooth, brittle, drooping, bright reddish-brown to orange colored. BITDS—Alternate, small, about i of an inch long, sharp-pointed, reddish-brown, covered by a single scale. LEAVES—Alternate, simple, narrowly-lanceolate, very long-pointed, tapering or slightly rounded at base, finely serrate on margin, usually smooth and dark green above, pale green below. LEAF-SCARS—Alternate, narrow, with 3 bundle-scars in a lunate line. Terminal scar often larger than lateral ones. Stipulo-scars large and prominent. FLOWERS—Appeal in March or April before the leaves. Staminate and pistillate flowers oc- cur on separate trees, and both are borne in drooping aments or catkins from 1-3 inches long. FRUIT—A reddish-brown, smooth, ovate capsule which splits open and liberates many small seeds. Seeds cohered with a dense tuft of fine long hairs. WOOD—Diffuse-porous; with very inconspicuous medullary rays; reddish-brown, soft, weak, firm, close-grained, not durable. Weighs about 28 lbs. per cubic foot. Used mainly for fuel and charcoal. DISTINGUISHING CHARACTERISTICS—The Black Willow is the largest of our native Wil- lows. The rough thick-scaled, biackish-brown bark is characteristic. The narrowly-lanceolate and short-petioled leaves which are always smooth or nearly so are also distinctive. The trunks often occur 'n small groups. The slender drooping branches are easily broken off at their ends. RANGE—New Brunswick to Florida, west to Dakota, Kansas, southern Arizona and central California. DISTRIBUTION IN PENNSYLVANIA—Throughout the State. Most common in eastern and southern parts. HABITAT—Prefers moist or wet situations like banks of streams and lakes. Requires plenty of light. Occasionally found on moist, gravelly and sandy soil. IMPORTANCE OF THE SPECIES—The Black Willow is the largest tree-willow native to our flora and is vory conspicuous in its appearance. It is of no present or prospective value except as a soil coaserver and to a limited extent as a producer of fuel wood and charcoal. Other more valuable and more attractive tree«? should be grown in place of It. > f
