Rhus lanceolata, the prairie sumac, is a species of plant native to the south-western United States (Texas, Oklahoma, Arizona, New Mexico), and northern Mexico (Coahuila, Nuevo León and Tamaulipas).
Rhus lanceolata is a shrub or small tree up to 9 m (30 feet) tall, reproducing by means of underground rhizomes. Leaves are pinnately compound with 13-17 lanceolate leaflets and a winged rachis. Leaflets are entire (untoothed) or with small teeth, green and shiny above but whitish and pubescent below. Flowers are born in a panicle up to 14 cm (5.6 inches) tall. Flowers are white to greenish. Fruits are lens-shaped, about 6 mm (0.25 inches) across, dark red and hairy.
Birds eat the fruit during the winter, and deer forage the foliage. The tannin-containing leaves have been used to tan leather.
