Nomenclatural notes on alien invasive vascular plants in China (2).

Some literatures recorded on the invasive plants in China are confused. Authors from the different regions in different time treated same species with different scientific names, or different species with same Chinese name, especially in the local reports. All those made it much worse in the study of alien invasive plants in China. This work reports twenty confused species, includes their scientific and Chinese names, synonyms, their origin, distribu鄄 tion in China, and necessary discussions.
