QUAKING ASP rSpiiliis trentuloid^s, fi-LimiloidiS refers to the fluttering habit of the leaves. ISIost widely distributed tree of North America. Prefers a rather moist sandy soil and gravelly hillsides. Small, slender, rarely reach- ing the height of fifty feet, but credited with one hundred feet in northern Arizona at an elevation of 8,000 feet above the sea. Grows rapidly and forms a narrow round-topped head. Roots large, vig- orous and stoloniferous. Bark.—On old trees near the base almost black ; higher on the trunk and on young stems, pale greenish brown or yellow brown or nearly white, often roughened with horizontal bands or wart-like ex- crescences and marked below the branches with large, dark, lunate scars. Branchlets at first red brown, and shining, turning finally to a light gray, afterward becoming dark gray, for tuo or three years much roughened by leaf-scars. The sweet inner bark in early spring is used as food by the Indians of the north. Wood.—Light brown, sapwood nearly white, soft, close-grained, neither strong nor durable. Largely used in the manufacture of paper ; and in the west for flooring and turnery. Burns freely when green. Sp. gr., ; weight of cu. ft., lbs.

Feather-veined, midrib and primary veins conspicuous. They come out of the bud involute, smooth, light green, shining, ciliate on margins, when full grown are thin, dark ^> green, shining above, pale, dull, yellow , =Mi™ green beneath.
