USDA Plants has this species occurring only in Texas, Okalhoma, and Louisiana, distribution data here taken from Jepson 2012. Look to the gray-green leaves with dull surfaces of the leaves to help identify this species. The whitish clusters of berries are also distinctive of this genus, along with the large leaves.
