ABSTRACT Historical records indicate that Matelea decipiens (Asclepiadaceae), oldfield milkvine or climbing milkweed, is known from Jackson, Saline, and Williamson counties in southern Illinois, where it is listed as endangered. Although a previous unvouchered occurrence has been noted in the Illinois Natural Heritage database, a recent collection from Monroe County, reported herein, officially extends the range north and west in the state.
