A tree, native of North America, with an irregularly growing crown. At some places specimen of over 20m, sometimes 30 m, can be found there. It branches rather low, sometimes creating a multiple-trunked tree with many, strongly pendent twigs. The trunk is irregular with deep grooves and many irregularities. The leaf is ovate-lanceolate, long acuminate and shiny green. The underside is duller. The top half of the leaf margin is sharply toothed and both sides of it are rough to the touch. In autumn it turns strikingly golden yellow. After an inconspicuous inflorescence the small stone fruits appear and colour from orange to black purple. These may persist all winter. The wood is useful and the young, flexible twigs were once used for whips.
