Abstract

Through extensive field work and careful examination of specimens, live plant photos, and related publications of Aristolochia, we conclude that A. austroyunnanensis and A. dabieshanensis are distinct species. Meanwhile, Aristolochia hyperxantha, a new species from northwestern Zhejiang, China, is described and illustrated. The new species is similar to A. mollissima in the flower color, but it differs in the indumentum and shape of leaf. Aristolochia hyperxantha is also similar to A. dabieshanensis in the leaf shape, but it differs in the shape and color of flower.
