Opuntia humifusa sensu stricto (Cactaceae): New to Kentucky (U.S.A.) and confirmed in the Unglaciated Appalachian Plateaus
A new population of Opuntia humifusa (Raf.) Raf. was found in Pike County, Kentucky. Consequent examination of other misidentified populations in Kentucky (Harlan and Pike counties) and West Virginia (Jackson County) provides the first known occurrences of Opuntia humifusa (sensu stricto) in Kentucky and a confirmed range extension into the Unglaciated Appalachian Plateaus Province.
