Abstract:

We found four new records of Amaranthus exotic weeds in Altay, Ili, Changji, Tacheng, and Hami during a field survey of weeds in northern and eastern Xinjiang. We recorded three species and one variety, respectively, of Amaranthus hybridus L., Amaranthus powelli S. Watson, Amaranthus viridis L., and Amaranthus retroflexus L. var. delilei (Richter & Loret) Thell that have not yet been found in this region. There are small populations of A. hybridus L. in Xinyuan, Yili, Urumqi, and Hami. A. viridis L. is only found in multiple populations in the Wusu Chepaizi reclamation area. A. retroflexus L. var. delilei (Richter & Loret) Thell. is only distributed in a small portion of Shihezi City. A. powellii S. Watson is only found in Balikun County, Hami City. The discovery of these newly recorded plants is of great significance to the study of the flora and species diversity of Amaranthus in Xinjiang, and also provides an important basis and new data for the study of their geographical distribution and of the spread and effective detection of invasive weeds. Specimens from the recorded species are kept in the Herbarium of Shihezi University.
