Rhus Nigricans Sumacs are shrubs and small trees that can reach a height of 3.3–32.8 ft. The leaves are spirally arranged; they are usually pinnately compound, though some species have trifoliate or simple leaves. The flowers are in dense panicles or spikes 2.0–11.8 in long, each flower very small, greenish, creamy white or red, with five petals.
Fossil representatives abundant in shales of the early Middle Eocene of the Green River Formation in Utah, Colorado, and Wyoming, and it is clear that the family was an important component of vegetation that surrounded the large lakes in which these shales were deposited.
