Abstract: During the plant diversity survey in Xinjiang in 2022－2023, the author found a Solanaceae plant in Hami City, Xinjiang, which had not been reported in the literature or recorded in specimens in China, and was distinctly different from other Solanaceae plants in China. Through literature review and comparative morphological characterization, it was identified asSolanum nitidibaccatumBitter., a newly recorded plant in China. Investigation for two consecutive years found that this species has multiple wild populations in Hami City, Xinjiang and has a tendency to spread. This paper, based on the English description of the morphological characters ofS. nitidibaccatumBitter., describes its morphological characteristics in Chinese in combination with the voucher specimen, and reports its geographic distribution and biological characteristics. It aims to provide new information for the study of species diversity of Solanaceae and the monitoring and control of invasive alien plants. The voucher specimen is preserved in the Herbarium of Shihezi University (SHI).

Key words: Solanum nitidibaccatumBitter., new record species, Solanaceae, China, Xinjiang
