New records of eleven angiosperm taxa are given for the Autonomous Region of Ningxia, China. Eight taxa, viz. Bromus carinatus, B. hordeaceus subsp. pseudothominei, Carduus acanthoides, Cynodon dactylon, Festuca arundinacea subsp. orientalis, Senecio vulgaris, Stellaria pallida and Tripleurospermum perforatum, are new to the flora of Ningxia. The spontaneous occurrence of Melilotus officinalis is reported for the first time from Ningxia. Poa annua, which is given in the ‘Flora Sinensis in Area Tan-Yang’ for Ningxa but not included in the ‘Flora Ningxiaensis’, is confirmed for Ningxia. Polygonum aviculare subsp. rectum is the first report of an infraspecific taxon of this polymorphic species for Ningxia. Of these eleven taxa Festuca arundinacea subsp. orientalis, Bromus carinatus, B. hordeaceus subsp. pseudothominei, Polygonum aviculare subsp. rectum and Tripleurospermum perforatum were found exclusively in Lolium perenne lawns, indicating their introduction with lawn seeds. Cynodon dactylon was found at down-trodden parts of Lolium perenne lawns but also as a garden weed. Melilotus officinalis was found in ruderal sites, Poa annua, Senecio vulgaris and Stellaria pallida were found only in watered ornamental gardens.
