Sugar Sumac - Rhus ovata
An evergreen tree with a thick trunk but less than 25 feet in height, this is a sumac of dry sites in southern California and central Arizona. It grows to elevations of 5,000 feet and its tolerance of poor soils makes it a good species for erosion control in the desert environment. The bark is grayish-brown and the trunk forked near the ground. The leaves are evergreen, pointed at the tip, rounded at the base, and leathery. The flowers are small and borne in dense, upright clusters. The fruits are less than a ½-inch in diameter, tightly clustered, reddish, and sticky.
