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Asplenium trichomanes L.
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.trichomanes L.ssp.trichomanes,喜钙亚种
A.trichomanes L. ssp.inexpectans Lovis,四倍亚种A.trichomanes L.ssp. quadrivalens D.E.Meyer emend.
Lovis,粗轴亚种A.trichomanes L.ssp.pachyrachis(Christ)Lovis et Reichst.和哈如变种A.trichomanes L.
var.harovii Moore emend.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.trichomanes L.var.centrochinense Christ(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。

Abstract:

 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.
