| 摘要: |
| 越南北部喀斯特地区洞穴生境独特，其蕨类植物多样性尚未被完全认知。为厘清该区域蕨类植物资源，本研究于2025年5月对越南北部宣光省(Tlnh Tuyên Quang)与高平省(Tlnh Cao Bang)的洞穴生境进行了植物专项调查。通过标本采集、形态学观察，并结合相关文献与馆藏标本进行比对鉴定，发现越南蕨类植物1个新记录属，即荚囊蕨属Cleistoblechnum Gasper & Salino;3个新记录种，即荚囊蕨Cleistoblechnum eburneum (Christ) Gasper & Salino、洞生耳蕨Polystichum cavernicola Li Bing Zhang & H.He和多角铁角蕨Asplenium cornutissimum X.C.Zhang & R.H.Jiang。本研究提供了上述新记录种的详细形态描述、地理分布信息及其彩色图片。本次发现证实了越南北部喀斯特地区是蕨类植物多样性的重要区域，上述新记录的增补不仅拓展了蕨类植物在越南的分布范围，也为深入研究该区域植物区系与生物地理学提供了新资料。 |

| Abstract: |
| The karst cave habitats in northern Vietnam are unique,and their fern diversity has not been fully understood.To clarify the fern plant resources in this region,a specialized plant survey was conducted in May 2025 in the cave habitats of Tuyen Quang province (Tlnh Tuyên Quang) and Cao Bang province (Tlnh Cao Bằang) in northern Vietnam.Through specimen collection,morphological observation,and comparison with relevant literature and herbarium specimens,one fern genus Cleistoblechnum Gasper & Salino was identified as a new record for Vietnam.In addition,three fern species were identified as new records for Vietnam,which were Cleistoblechnum eburneum (Christ) Gasper & Salino,Polystichum cavernicola Li Bing Zhang & H.He,and Asplenium cornutissimum X.C.Zhang & R.H.Jiang.This study provides detailed morphological descriptions,geographical distribution information,and color figures for these newly recorded species.These findings confirm that the karst area of northern Vietnam is an important region for fern diversity.The addition of these new records not only expands the known distribution range in Vietnam but also provides new data for in-depth research on the flora and biogeography of this region. |
