Clematis jialasaensis var. macrantha and C. napoensis (Ranunculaceae), another two new synonyms of C. armandi from China

Based on consultation of literature, survey of specimens (including type material), and observations of living plants in the wild, we confirm that Clematis jialasaensis var. macrantha and C. napoensis (Ranunculaceae), described respectively from northeastern Yunnan and southwestern Guangxi, China, actually belong to C. armandi, a species widely distributed in the country. We therefore place both C. jialasaensis var. macrantha and C. napoensis in synonymy with C. armandi. We also determine that two collections of Clematis, J.M. Delavay 4 and J.M. Delavay 5146, from Tchen-fong Chan in northeastern Yunnan, China, the type locality of C. jialasaensis var. macrantha, also belong to C. armandi. These two collections have been previously referred to C. meyeniana or C. finetiana.
