Abstract

Gleicheniaceae is an early diverging lineage of leptosporangiate ferns. Although the family can be readily recognized by the pseudodichotomous branching pattern of its fronds, generic circumscription has long been debated. Phylogenetic analyses based on genomic data supported the monophyly of six genera (Dicranopteris, Diplopterygium, Gleichenella, Gleichenia, Rouxopteris, and Stromatopteris) but indicate the paraphyly of Sticherus. To accommodate this latter result, we describe a new genus, Sticheropsis, gen. nov., segregated from Sticherus. We provide a new taxonomic treatment of Gleicheniaceae, including an identification key to all eight genera, descriptions of the genera with comments and notes concerning geographic distributions and phylogenetic affinities, as well as an overview of the morphology of the family with a revised and unified terminology for the fronds. We recognize 149 species plus two hybrids for the family, distributed into eight genera, and propose six new combinations.

蕨类植物 Gleicheniaceae 科的分类，并描述了从 Sticherus 分离出来的一个新属

鳞叶蕨科（Gleicheniaceae）是鳞叶蕨类植物中分化较早的一族。虽然该科很容易通过其叶片的假二分枝模式辨认出来，但其属的划分一直存在争议。基于基因组数据的系统发育分析支持 6 个属（Dicranopteris、Diplopterygium、Gleichenella、Gleichenia、Rouxopteris 和 Stromatopteris）的单系性，但指出 Sticherus 属于旁系。为了适应后一种结果，我们描述了一个新属，Sticheropsis，gen. nov.我们提供了一个新的 Gleicheniaceae 的分类学处理方法，包括所有 8 个属的识别钥匙、属的描述以及关于地理分布和系统发育亲缘关系的注释和说明，以及对该科形态学的概述，并修订和统一了叶片的术语。我们确认该科有 149 个种和 2 个杂交种，分布在 8 个属中，并提出了 6 个新的组合。

期刊介绍： The Botanical Journal of the Linnean Society publishes original papers on systematic and evolutionary botany and comparative studies of both living and fossil plants. Review papers are also welcomed which integrate fields such as cytology, morphogenesis, palynology and phytochemistry into a taxonomic framework. The Journal will only publish new taxa in exceptional circumstances or as part of larger monographic or phylogenetic revisions.
