Roundleaf Greenbrier

Smilax rotundifolia, also known as roundleaf greenbrier or common greenbrier, or bamboo vine in parts of the South, is a woody vine native to the southeastern and eastern United States and eastern Canada. It is a common and conspicuous part of the natural forest ecosystems in much of its native range. The leaves are glossy green, petioled, alternate, and circular to heart-shaped. They are generally 5–13 cm long. Common greenbrier climbs other plants using green tendrils growing out of the petioles.
