Stephania is a genus of flowering plants in the family Menispermaceae. It includes 70 species native to tropical and southern Africa, eastern and southern Asia, Australia, and the tropical Pacific Islands. They are herbaceous perennial vines, growing to around four metres tall, with a large tuber. The leaves are arranged spirally on the stem and are peltate, with the leaf petiole attached near the centre of the leaf. The name Stephania comes from the Greek, "a crown". This refers to the anthers being arranged in a crown-like manner.
