Ailanthus altissima (Miller) Swingle
(Tree of Heaven)
Ailanthus gladulosa Desfontaines
Ailanthus altissima is found in middle elevations growing at the roadside and in nearby swales. It is generally an unwanted interloper. It has pinnately compound leaves which are coarsely dentate. Portions of the tree take on a reddish hue by mid-summer because the samaras become partially red in color. The winter twigs are very thick and light brown, with a light brown pith. There are around 8 or 9 bundle scars in the leaf scars. The buds are hemispheric.
