摘　　要：综合运用孢粉学、细胞学、生态学和形态学的证据 ,处理了中国产铁角蕨AspleniumtrichomanesL .的种下分类问题 ,将其划分为 4个亚种和 1个变种 :原亚种A .trichomanesL .ssp .trichomanes,喜钙亚种A .trichomanesL .ssp .inexpectansLovis,四倍亚种A .trichomanesL .ssp.quadrivalensD .E .Meyeremend .Lovis,粗轴亚种A .trichomanesL .ssp .pachyrachis (Christ)LovisetReichst.和哈如变种A .trichomanesL .var.haroviiMooreemend .Midle ,并提供了它们在中国的分布情况。查阅研究中国科学院植物研究所(PE)的标本时发现 ,一些定名为A .trichomanesL .var.centrochinenseChrist(华中变种 )的模式标本碎片在形态上和倍性上均不同于已知分类群 ,认为应给予其新种的分类地位。With the evidence from palynological, cytological, ecological and morphological data, the subspecific taxonomy of Asplenium trichomanes L. from China is carried out. Four subspecies and one variety, i.e. A. trichomanes L. ssp. trichomanes, A. trichomanes L. ssp. inexpectans Lovis, A. trichomanes L. ssp. quadrivalens D. E. Meyer emend. Lovis, A. trichomanes L. ssp. pachyrachis (Christ) Lovis et Reichst. and A. trichomanes L. var. harovii Moore emend. Midle are recognized from China. The distribution of each subspecies and variety is also presented. Some fragments of a type specimen named as A. trichomanes L. var. centrochinense Christ in PE are found to be different from the known taxa of A. trichomanes L. complex both morphologically and cytologically, and therefore are regarded representing a new species.
