Rhus glabra, the smooth sumac,[2] (also known as white sumac, upland sumac, or scarlet sumac)[3] is a species of sumac in the family Anacardiaceae, native to North America, from southern Quebec west to southern British Columbia in Canada, and south to northern Florida and Arizona in the United States and Tamaulipas in northeastern Mexico.Smooth sumac has a spreading, open habit, growing up to 3 m (9.8 ft) tall, rarely to 5 m (16 ft). The leaves are alternate, 30â50 cm (12â20 in) long, compound with 11â31 oppositely paired leaflets, each leaflet 5â11 cm (2â4+1?4 in) long, with a serrated margin. The leaves turn scarlet in the fall. The flowers are tiny, green, produced in dense erect panicles 10â25 cm (4â10 in) tall, in the spring, later followed by large panicles of edible crimson berries that remain throughout the winter. The buds are small, covered with brown hair and borne on fat, hairless twigs. The bark on older wood is smooth and grey to brown.
