Description of Greenbriar, Roundleaf (Smilax rotundifolia):

Roundleaf greenbriar is a woody vine that climbs. If it has nothing to climb, it will spread across the ground. The stems may be rounded or angled, have flattened sharp stout green spines that have blackened tips, but spines may be isolated to the lower stem parts of woody plants. Plants in colder zones may die back each year. The numerous tendrils emerge at the leaf stalk.
