Description
Summary:S.Jin Zeng, G.D.Tang & Miao Liao, (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 Wall., which has been included in L.. It is different from all former species by the broadly ovate corolla lobes, purple-red corolla and connivent corona tip slightly exceeding the corolla throat. Meanwhile, G.D.Tang & Miao Liao, is proposed as replacement name for Y.Wan, which was considered a synonym of (Blume) Liede & Khanum but is here reinstated as a distinct species because of significant morphological differences.
