山西省被子植物5个新记录种

Five newly recorded species of angiosperms from Shanxi Province

【目的】丰富山西省被子植物种质资源信息,促进中条山生物多样性和森林生态系统研究。【方法】在大量野外植被调查工作基础上,通过标本鉴定、资料查阅和专家咨询,对中条山植物标本、典型特征照片进行整理。【结果】小酸模(Rumex acetosella L.)、伏毛银莲花(Anemone narcissiflora subsp.protracta(Ulbrich) Ziman&Fedoronczuk)、弯曲碎米荠(Cardamine flexuosa With.)、卢氏凤仙花(Impatiens lushiensis Y. L. Chen)、小酸浆(Physalis minima L.)等5种被子植物在山西未有分布记录。【结论】该5种植物隶属于5科5属,为山西省被子植物分布新记录,新记录发现不仅丰富了山西省被子植物种质资源信息,而且对研究中条山生物多样性和森林生态系统具有重要意义。

[Objective]The aim is to enrich the angiosperm germplasm resources in Shanxi Province,and promote research on biodiversity and forest ecosystems in Zhongtiao Mountain area.[Methods]Photoes of plant specimens and their typical features from Zhongtiao Mountains were collected through specimen identification,data access,and expert consultation,by conducting an extensive field survey of vegetation.[Results]Five species of angiosperms were newly recorded in Shanxi Province,including viz.Rumex acetosella L.,Anemone narcissiflora subsp.protracta(Ulbrich)Ziman&Fedoronczuk,Cardamine flexuosa With.,Impatiens lushiensis Y.L.Chen,and Physalis minima L..[Conclusion]These plants belong to 5 families and 5 genera,which are newly recorded species of angiosperms from Shanxi Province.These discoveries enrich the angiosperms germplasm resources and provide a basis for the study of plant diversity and florogenesis in Zhongtiao Mountain Area.
