Isotrema hei Lei Cai & X.X. Zhu, a new species of Aristolochiaceae from Wenshan City, southeastern Yunnan, China, is described and illustrated. It resembles I. kunmingense and I. liangshanense in the shape and structure of the flower, but can be distinguished from both by the shape of leaf blade, bractlet and gynostemium; by the indumentum of petiole, leaf blade, bractlet and lower tube; and by the flower colour.
