Abstract: This paper reported a newly recorded genus of Poaceae in Guangdong, viz. Moliniopsis Hayata. This genus is monotypic with the type species, M. japonica (Hackel) Hayata, distributed in Russian Far East, Japan, South Korea and Southeast China (Anhui, Zhejiang, Jiangxi, Fujian). Recently, a population of this species was found in Conghua District, Guangzhou City, Guangdong Province, which is the southernmost population of this species. This new finding is of great significance for the future study of the geographical distribution and the origin and the spread of M. japonica. The vouchers are deposited in the herbarium of South China Botanical Garden, Chinese Academy of Sciences (IBSC).

Key words: Poaceae, new record; Moliniopsis japonica, Molinia
