Berberis swaseyi[4] (Texas barberry)[5] is a rare species of barberry endemic to the Edwards Plateau region of Texas. It grows in limestone ridges and canyons. The species is evergreen, with thick, rigid, five-to-nine foliolate leaves. Berries are dry or juicy, white to red, about 9–16 mm in diam.[6][7]
The compound leaves place this species in the group sometimes segregated as the genus Mahonia.[6][8][9][10]
