Magnoliids Aristolochia hainanensis subsp. yingjiangensis Aristolochia involuta Aristolochia obliqua China clarification taxonomy

Abstract

In this paper, Aristolochia involuta and A. hainanensis subsp. yingjiangensis, two new taxa from Yunnan, China, are described and illustrated. The former is similar to A. bambusifolia in the calyx limb, but differs in the flower size and leaf shape. The latter differs from A. hainanensis by its leaf shape, fruit size and distribution. And we also clarify the flower character of Aristolochia obliqua.
