摘　　要：【目的】调查赣南九连山地区的蕨类植物资源,为植物资源保护和利用提供依据。【方法】采用路线调查法对赣南地区分布的野生蕨类植物进行调查,并结合形态学和分子生物学方法对存疑种进行研究。【结果】在江西省龙南市龙南镇石峡山发现对囊蕨属中国新记录——多羽对囊蕨[Deparia confluens(Kunze)M.Kato]。系统发育分析表明,该种与D.biserialis(Baker)M.Kato﹑阔基假蹄盖蕨、二型叶对囊蕨近缘,但其叶片狭披针形,厚草质,侧生分离羽片15~30对,羽状浅裂至半裂,小脉2~4对,因此易于与这些近缘种区分。根据世界自然保护联盟红色名录标准,暂将其评估为近危种。凭证标本保存于中国科学院昆明植物研究所标本馆(KUN)和中国科学院庐山植物园标本馆(LBG)。【结论】多羽对囊蕨的发现,补充了其种群分布范围,进一步丰富了中国蕨类植物资源和物种多样性。【Objective】The fern resources in Jiulianshan area of southern Jiangxi Province were investigated to provide basis for the protection and utilization of the plant resources.【Method】Wild ferns in southern Jiangxi were investigated by route survey method,among which the suspected species were examined by morphological analysis and molecular biological methods.【Result】Deparia confluens(Kunze)M.Kato,which is a new Chinese record of Deparia was found in Shixiashan,Longnan Town,Longnan City,Jiangxi Province.Phylogenetic analysis revealed its close relations to D.biserialis(Baker)M.Kato,D.pseudoconilii(Seriz.)Seriz.,and D.dimorphophylla(Koidzumi)M.Kato,but can be easily distinguished by its acicular and thick lamina,15-30 pairs of lateral pinnae,pinnately lobed to pinnatifid,and 2 to 4 pairs of veinlets.According to the International Union for Conservation Nature Red List Categories and Criteria,it is temporarily assessed as near threatened species.Voucher specimens are stored in the Herbarium of Kunming Institute of Botany,Chinese Academy of Sciences(KUN)and Lushan Botanical Garden Herbarium,Chinese Academy of Sciences(LBG).【Conclusion】This new record is complementary to the distribution of Deparia confluens populations,and further enriches the fern resources and species diversity in China.
