Abstract

Abstract The pantropical genus Tectaria Cav. (Tectariaceae) is one of the largest fern genera. It has been estimated to contain ca. 210 mostly tropical species in Africa, the Americas, Asia, and the Indian Ocean and Pacific Ocean islands. Tectaria had perhaps been the most confusing fern genus in terms of its circumscription and phylogeny. Recent studies have recircumscribed Tectaria and resolved the relationships within the genus. However, no efforts have been made to propose an infrageneric classification of the genus based on molecular and morphological evidence. In the present study, we synthesize chloroplast and nuclear DNA evidence, morphology, and/or distribution information and divide Tectaria into four subgenera: Tectaria subg. Ctenitopsis (Ching ex Tardieu & C. Chr.) Li Bing Zhang & Liang Zhang (comb. & stat. nov.), Tectaria subg. Phlebiogonium (Fée) Li Bing Zhang & Liang Zhang (comb. & stat. nov.), Tectaria subg. Tectaria, and Tectaria subg. Tectaridium (Copel.) Li Bing Zhang & Liang Zhang (comb. & stat. nov.). The latter three are further divided into seven, two, and two sections, respectively. Sixteen generic names are synonymized to individual infrageneric taxa, while four generic names are only synonymized to Tectaria because of inadequate data. A key to the infrageneric taxa is given. A nomenclatural account of each infrageneric taxon is provided.

基于分子和形态学证据的蕨类植物荆芥属的分类[j]

泛热带仙人掌属。是最大的蕨类植物属之一。据估计，在非洲、美洲、亚洲、印度洋和太平洋岛屿上大约有210种，主要是热带物种。就其界限和系统发育而言，木蕨可能是最令人困惑的蕨类属。最近的研究重新界定了茶树属，并解决了属内的关系。然而，没有人根据分子和形态证据提出该属的近属分类。在本研究中，我们综合了叶绿体和细胞核的DNA证据、形态和/或分布信息，并将其划分为四个亚属:栉水母(Ching ex Tardieu & C. Chr.)张李兵和张亮(梳)。& stat. 11)，浙江分公司。静脉导管(f)张李兵张亮(梳)& stat. 11)，浙江分公司。泰克塔利亚和泰克塔利亚。Tectaridium(科普尔铜镍合金)。张李兵和张亮(梳)。&统计11月)。后三部分又分别分为七节、二节和二节。有16个属名与单属分类群具有同义性，而4个属名由于资料不足，仅与赤藓属有同义性。本文还给出了亚属分类群的钥匙。对每一个属内分类单元都作了命名说明。

期刊介绍： The Annals of the Missouri Botanical Garden is a quarterly international journal primarily devoted to systematic botany and evolutionary biology. We encourage submissions of original papers dealing with significant advances in the taxonomy, phylogeny, biogeography, paleobiology, and evolution of plants, and in conservation genetics and biology, restoration ecology, and ethnobiology, using morphological and/or molecular characters, field observations, and/or database information. We also welcome reviews and papers on conceptual issues and new methodologies in systematics. Important floristic works will also be considered. Symposium proceedings discussing a broader range of topical biological subjects are also published, typically once a year. All manuscripts are peer-reviewed by qualified and independent reviewers.
