Abstract

We conducted a morphological re-examination of Vincetoxicum matsumurae (T.Yamaz.) H.Ohashi (= Cynanchum matsumurae T. Yamaz.) and Tylophora tanakae Maxim. Corona and pollinarium of V. matsumurae agreed with those of Tylophora. Thus, we propose a new combination Tylophora matsumurae. (T.Yamaz.) T. Yamash. & Tateishi. Although T. matsumurae resembles T. tanakae, the former is distinguished from the latter in having oblong corolla-lobes, shorter inflorescence-rachis, narrower fruits and smaller seeds.
