摘要

摘要细蕨科细蕨是细孢子蕨类植物中分布最广的一种。根据叶绿体rbcL基因的序列，我们识别出两个分支，它们在鳞片和叶片形态上有所不同。这表明，至少有两个进化上不同的物种包含在目前的切齿人的范围内。

At Least Two Evolutionarily Distinct Species within Histiopteris incisa Inferred from Molecular and Morphological Evidence

Abstract. Histiopteris incisa (Dennstaedtiaceae) is one of the most cosmopolitan species among the leptosporangiate ferns. Based on sequences of the chloroplast rbcL gene, we recognize two lineages within H. incisa, and these differ in scale and leaf morphology. This suggests that at least two evolutionarily distinct species are contained within present circumscriptions of H. incisa.
