Round-leaved greenbrier (Smilax rotundifolia) is a woody climbing vine that can reach a length of over four metres. Main stems are rounded and bear stout flattened prickles; its branchlets are sometimes four-angled. Leaves are alternate and simple, 5 10 cm long, with an ovate blade and a heart-shaped base. Plants are unisexual, with the small green male and female flowers clustered in rounded umbels whose stems arise from the leaf angles. Each female umbel produces a few blue-black, mostly two seeded berries.
