Trillium texanum, the Texas trillium or Texas wakerobin, is a species of flowering plant in the family Melanthiaceae.[3][4][5] It is found in east Texas, extreme southwestern Arkansas and extreme northwestern Louisiana,[6] typically in forested wetland habitat.[7] Due to its limited range, it is designated as an imperiled species.[1] In Louisiana, it is critically imperiled.[5]
