Flowers: Staminate and pistillate borne on separate trees, several in a cluster, greenish-yellow, appearing as the leaves begin to unfold.
Fruit: Borne in pairs, in drooping clusters, composed of a curved wing with a seed at the base, greenish-yellow, up to 2 inches long.
Wood: Light weight, soft, close-grained, white.
Uses: Paper pulp, interior finishing, furniture.
Habitat: Moist woods.
Range: Vermont across to Saskatchewan, south to Texas, east to Florida.
Distinguishing Features: The Box Elder most nearly resembles ashes, but differs by its green or glaucous twigs and its paired fruits.
Growth Form: Medium tree up to 65 feet tall; trunk diameter up to 2 1/2 feet; crown broad, with several upright branches.
Bark: Dark brown to black, smooth when young, soon becoming furrowed and scaly.
Twigs: Slender, brown, smooth, often with pale lenticels; leaf scars opposite, U-shaped, with 3-7 bundle traces.
Buds: Pointed, dark brown, finely hairy, up to one-fourth inch long.
Leaves: Opposite, simple; blades up to 6 inches long and nearly as broad, palmately 3- to 5-lobed, drooping on the sides, the edges of the leaves sparsely and coarsely toothed, green and smooth on the upper surface, yellow-green and smooth or hairy on the veins on the lower surface; leafstalks up to 5 inches long, smooth or hairy. The leaves turn yellow in the autumn.
Flowers: Staminate and pistillate borne separately, but sometimes on the same tree, in dense clusters, yellowish, appearing as the leaves unfold.
Fruit: Borne in pairs, composed of a wing with a seed at the base, reddish-brown to greenish, up to 1 inch long.
Wood: Heavy, strong, coarse-grained, brown.
Uses: Furniture, cabinets.
Habitat: Rich woodlands.

Leaves: Opposite, simple; blades up to 6 inches long, nearly as broad, palmately 3- to 5-lobed, the edges of the leaves sharply toothed to nearly toothless, pale green and smooth on the upper surface, white or gray and either smooth or hairy on the lower surface; leafstalks smooth or finely hairy, up to 4 inches long.
Flowers: Staminate and pistillate borne separately, but sometimes on the same tree, in dense clusters, bright red or yellow, opening in February and March before the leaves begin to unfold.
Fruit: Borne in pairs, composed of an erect wing with a seed at the base, red or yellow, up to 1 inch long.
