Habitat and Range.—Cool, rocky or sandy woods.
Nova Scotia to Lake Superior.
Maine,—abundant, especially northward in the forests; New Hampshire and Vermont,—common in highland woods; Massachusetts,—common in the western and central sections, rare towards the coast; Rhode Island,—frequent northward; Connecticut,—frequent, reported as far south as Cheshire (New Haven county).
South on shaded mountain slopes and in deep ravines to Georgia; west to Minnesota.
Habit.—Shrub or small tree, 15-25 feet high, with a diameter at the ground of 5-8 inches; characterized by a slender, beautifully striate trunk and straight branches; by the roseate flush of the opening foliage, deepening later to a yellowish-green; and by the long, graceful, pendent racemes of yellowish flowers, succeeded by the abundant, drooping fruit.
Bark.—Bark of trunk and branches deep reddish-brown or dark green, conspicuously striped longitudinally with pale and blackish bands; roughish with light buff, irregular dots; the younger branches marked with oval leaf-scars and the linear scars of the leaf-scales; the season's shoots smooth, light green, mottled with black.
In spring the bark of the small branches is easily separable, giving rise to the name "whistle wood."
