摘要

摘要基于形态学和分子证据，描述并说明了产于中国云南省的新种Cynanchumpingtaoi S.Jin Zeng, G.D.Tang & Miao Liao（芹菜科）。它的深心形至肾形叶片和钟状大花表明它是前 Raphistemma Wall.它的花冠裂片呈宽卵形，花冠呈紫红色，靠合的副花冠顶端略高于花冠喉部，这一点与以前所有的 Raphistemma 品种都不同。Cynanchumlonghushanense G.D.Tang & Miao Liao，nom. nov.被提议作为 Raphistemmabrevipedunculatum Y.Wan 的替代名称，Raphistemmabrevipedunculatum Y.Wan 曾被认为是 Cynanchumhooperianum (Blume) Liede & Khanum 的异名，但由于形态上的显著差异，在此被恢复为一个独立的种。

A new species and a replacement name in Cynanchum (Apocynaceae, Asclepiadeae) from China

Abstract Cynanchumpingtaoi S.Jin Zeng, G.D.Tang & Miao Liao, sp. nov. (Apocynaceae) from Yunnan Province, China, is described and illustrated based on morphological and molecular evidence. Its deeply cordate to reniform leaves and campanulate, large flowers show that it is a member of former Raphistemma Wall., which has been included in Cynanchum L.. It is different from all former Raphistemma species by the broadly ovate corolla lobes, purple-red corolla and connivent corona tip slightly exceeding the corolla throat. Meanwhile, Cynanchumlonghushanense G.D.Tang & Miao Liao, nom. nov. is proposed as replacement name for Raphistemmabrevipedunculatum Y.Wan, which was considered a synonym of Cynanchumhooperianum (Blume) Liede & Khanum but is here reinstated as a distinct species because of significant morphological differences.
