Seven newly recorded species from Xizang and Xinjiang in China

本文报道了6个中国被子植物新记录种及1个新记录亚种,分别是采自西藏的灰滨藜(Atriplex pallida)、类球花藜(Blitum litwinowii)、滨藜状藜(Chenopodium atripliciforme)、土耳其针茅(Stipa turkestanica)、扁果岩蓼(Polygonum cognatum subsp.chitralicum)及新疆的宝格达黄芪(Astragalus baitagensis)和神香草叶千屈菜(Lythrum hyssopifolia),观察了部分类群的微形态特征并提供了生境或形态图。凭证标本均存放于内蒙古大学植物标本馆(HIMC)。

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.
