摘 要 ：根据叶绿体rbcL和rps4-trnS序列及叶脉类型、孢子纹饰特征等证据,栗柄水龙骨Polypodiodes microrhizoma(C.B.Clarke ex Baker)Ching属于篦齿蕨属Metapolypodium Ching的范畴,因此将其组合到篦齿蕨属Metapolypodium Ching之下更合理。文中报道了该新组合种,即栗柄篦齿蕨Metapolypodium microrhizomum(C.B.Clarke ex Baker)S.G.Lu et L.H.Yang。
Abstract:According to evidence from chloroplast rbcL and rps4-trnS sequences,venation types,and ornamentation of spores,it is reasonable that Polypodiodes microrhizoma(C.B.Clarke ex Baker) Ching should be combined with Metapolypodium Ching.Therefore,a new combination species,Metapolypodium microrhizomum(C.B.Clarke ex Baker) S.G.Lu et L.H.Yang,is reported in this paper.
