摘要
鳞毛蕨亚属Nothoperanema（鳞毛蕨科）包括Acrophorus、Diacalpe、Nothoperanema 和Peranema 部分。这些部分之间的系统发育关系及其与教派的关系。鳞毛蕨属(Dryopteris subgenus Erythrovariae、鳞毛蕨科)尚不清楚。此外，之前的系统发育工作并未包括Stenolepia，根据形态学，Stenolepia 被认为是 Peranema 的重要近亲。在这项研究中，我们通过包括 Stenolepia 在内并利用六个质体区域（约 5,500 个字符）检查了 Nothoperanema 亚属内的系统发育关系。我们推断的系统发育揭示了这个教派。 Dryopsis不是单系的。 Nothoperanema 分支受到高度支持，并且包括教派。卫城，教派。迪亚卡尔佩，教派。诺托佩拉内玛，组。 Peranema、某些Dryopsis 物种和Stenolepia。通过重新检查诊断形态特征，我们在 Nothoperanema 亚属下建立并描述了两个新部分：sect。 Shiehia和教派。狭窄。这次修订容纳了从教派转移的新物种。 Dryopsis和Stenolepia，并使Nothoperanema亚属及其每个部分成为自然类群。最后，我们提供了一个包含形态比较的表格和章节的关键。
Abstract
Dryopteris subgenus Nothoperanema (Dryopteridaceae) includes sections Acrophorus, Diacalpe, Nothoperanema, and Peranema. Phylogenetic relationships among these sections and their relationship to sect. Dryopsis (genus Dryopteris subgenus Erythrovariae, Dryopteridaceae) are unclear. Additionally, previous phylogenetic work has not included Stenolepia, which has been suggested as an important relative of Peranema based on morphology. In this study, we examined phylogenetic relationships within subgenus Nothoperanema by including Stenolepia and utilizing six plastid regions (∼5,500 characters). Our inferred phylogeny revealed that sect. Dryopsis is not monophyletic. The Nothoperanema clade is highly supported, and includes sect. Acrophorus, sect. Diacalpe, sect. Nothoperanema, sect. Peranema, certain Dryopsis species, and Stenolepia. By re-examining diagnostic morphological characters, we establish and describe two new sections under subgenus Nothoperanema: sect. Shiehia and sect. Stenolepia. This revision accommodates new species transferred from sects. Dryopsis and Stenolepia, and makes subgenus Nothoperanema and each of its sections natural groups. Finally, we provide a table with morphological comparisons and a key to sections.
