Abstract

Aim: We aim to understand the plant diversity in the border areas of Xizang and Xinjiang. These border areas are the focus and hot spots of biodiversity conservation.
Method: In this study, plants were collected and photographed through field investigation, made into specimens, and sorted out and identified. The voucher specimens for each reported species were preserved in the Herbarium of Inner Mongolia University (HIMC).
Results: Six newly recorded angiosperm species and one sub-species in China were reported, of which Atriplex pallida, Blitum litwinowii, Chenopodium atripliciforme, Stipa turkestanica and Polygonum cognatum subsp. chitralicum were found in the Xizang Autonomous Region, while Astragalus baitagensis and Lythrum hyssopifolia were collected from the Xinjiang Uygur Autonomous Region.
Conclusion: The investigation of plants in the border areas of Xizang and Xinjiang with neighboring countries is relatively weak, and should be further strengthened in the investigation of flora and resources in the future. The discovery of new distributed plants is of great significance to the nature of the local flora and the attribution of the regionalization.
