Smilax pumila Walter

The red, pointed fruits and densely pubescent herbage of Smilax pumila are distinctive. In Louisiana, the dried leaves are used to prepare a tea for upset stomach.

The name Smilax humilis Miller, which predates S. pumila by 20 years and recently has been determined to apply also to this species, has been proposed for rejection (J. L. Reveal 2000). If that proposal is not adopted, the correct name will be S. humilis.

Subshrubs or vines; rhizomes black, knotted, 5–6 × 2 cm, often with white to pinkish stolons. Stems perennial, prostrate to clambering, branching, slender, to 1 m, ± woody, densely woolly-pubescent, usually prickly (especially at base).
