(A) Rows of Chinese Elm, Ulmus parvifolia Jacq. cvs. Allee and Drake in Lake County, Florida. Black square highlights the Allee cultivar tag; (B) Ulmus parvifolia cv. Allee tag; (C) Root galls on Ulmus parvifolia cv. Allee. White arrow indicates the distinctive round galls commonly produced by Meloidogyne enterolobii Yang and Eisenback, 1981.
