摘要
基于对甘肃省插岗梁省级自然保护区的野外实地考察,结合文献考证与标本鉴定研究,共确认了7种甘肃省新纪录植物,分别为:基芽耳蕨Polystichum capillipes(Baker)Diels、猫儿刺耳蕨Polystichum stimulans(Kunze ex Mett.)Bedd.、革叶蟹甲草Parasenecio caroli(C.Winkl.)C.Ren&Q.E.Yang、小兔耳风Ainsliaea nana Y.C.Tseng、松潘蒲儿根Sinosenecio sungpanensis(Hand.-Mazz.)B.Nord.、尾叶风毛菊Saussurea caudata Franch.以及流苏虎耳草Saxifraga wallichiana Sternb.。上述物种分别属于3科6属,并已记录其凭证标本并描述了形态鉴别特征。所有凭证标本均保存于西北师范大学植物标本室(NWTC)。这些新纪录的发现,丰富了甘肃省维管植物的物种多样性,也补充了该地区植物区系的基础资料,同时为深入研究当地生态系统的结构特征及植物的生态适应性提供了新的材料依据。
Based on field investigations in Chagangliang Provincial Nature Reserve in Gansu province,combined with literature research and specimen identification,a total of 7 new provincial-level record plants from Gansu province were confirmed.They are:Polystichum capillipes(Baker)Diels,P.stimulans(Kunze ex Mett.)Bedd.,Parasenecio caroli(C.Winkl.)C.Ren&Q.E.Yang,Ainsliaea nana Y.C.Tseng,Sinosenecio sungpanensis(Hand.-Mazz.)B.Nord.,Saussurea caudata Franch.,and Saxifraga wallichiana Sternb.These species belong to 3 families and 6 genera,and their voucher specimens have been recorded and their morphological identification characteristics have been described.All voucher specimens are preserved in the Plant Specimen Room of Northwest Normal University(NWTC).The discovery of these new records enriches the vascular plants species diversity of Gansu province and supplements the basic data of the plant flora in this region.At the same time,it provides a new material basis for in-depth research on the structural characteristics of the local ecosystem and the ecological adaptability of plants.
