甘肃省维管植物新记录6种OA

To improve the floristic data of vascular plants in Gansu Province and fill the gaps in regional plant diversity surveys,this study identified 6 new records of vascular plants in Gansu Province through systematic field resource investigations,specimen collection,rigorous indoor specimen identification,and comparison of morphological characteristics.These species are Allium henryi C.H.Wright,Pellionia brevifolia Benth.,Hymenophyllum levingei C.B.Clarke,Oreocharis lancifolia(Franch.)Mich.Möller&A.Weber,Swertia dichotoma var.punctata T.N.Ho&J.X.Yang,and Lotus frondosus Freyn.The discovery of these 6 new vascular plant records not only enriches the species composition of the vascular plant flora in Gansu Province and fills the gaps in the distribution records of these species in the region,but also provides new clues for exploring the connections between the flora of Gansu Province and those of surrounding regions as well as the pathways of species diffusion.Meanwhile,it lays a solid foundation of basic data for the precise protection of regional plant diversity,the scientific planning and rational utilization of vegetation resources,and the in-depth study on the evolution of vascular plant flora.
