history: Macfadyena unguis-cati was introduced into the US in 1947 as an ornamental vine. In the US, it is found in Hawaii, Texas, LA, FL, Georgia and South Carolina. The plant is currently present on every continent except Antarctica. Outside of its native range, it is widely considered to be invasive due to its prolific growth habit. Its common name comes from its tripartite hooked tendrils which resemble a claw and allow the vine to adhere to tree bark. In its native range, the plant was used medicinally for treatment of dermatitis and other ailments.
