Vine very vigorous, sometimes, when without support, shrubby and
only three or four feet high; when growing in the shade often
sending down aerial roots. Wood hard, bark smooth, not scaling,
with prominent warty lenticels; shoots short-jointed, angled, with
fine scurfy pubescence; diaphragms absent; tendrils intermittent,
simple. Leaves small, broadly cordate or roundish; petiolar sinus
wide, shallow; margin with obtuse, wide teeth; not lobed; dense in
texture, light green color, glabrous above, sometimes pubescent
along veins below. Cluster small (6-24 berries), loose; peduncle
short; pedicels short, thick. Berries large, globular or somewhat
oblate, black or greenish-yellow; skin thick, tough and with a
musky odor; pulp tough; ripening unevenly and dropping as soon as
ripe. Seeds flattened, shallowly and broadly notched; beak very
short; chalaza narrow, slightly depressed with radiating ridges
and furrows; raphe a narrow groove. Leafing, flowering and
ripening fruit very late.

The habitat of this species is southern Delaware, west through
Tennessee, southern Illinois, southeastern Missouri, Arkansas (except
the northwestern portions), to Grayson County, Texas, as a northern
and western boundary, to the Atlantic Ocean and the Gulf on the east
and south. It becomes rare as one approaches the western limit but is
common in many sections of the great region outlined above, being most
abundant on sandy, well-drained bottom lands and along river banks and
in swampy, thick woodlands and thickets. The climate most
