Molecular phylogenetic studies based on Sanger sequences have shown that Cyperaceae tribe Fuireneae s.l. is paraphyletic. However, taxonomic sampling in these studies has been poor, topologies have been inconsistent, and support for the backbone of trees has been weak. Moreover, uncertainty still surrounds the morphological limits of Schoenoplectiella, a genus of mainly small, amphicarpic annuals that was recently segregated from Schoenoplectus. Consequently, despite ample evidence from molecular analyses that Fuireneae s.l. might consist of two to four tribal lineages, no taxonomic changes have yet been made. Here, we use the Angiosperms353 enrichment panel for targeted sequencing to (i) clarify the relationships of Fuireneae s.l. with the related tribes Abildgaardieae, Eleocharideae, and Cypereae; (ii) define the limits of Fuireneae s.s., and (iii) test the monophyly of Fuireneae s.l. genera with emphasis on Schoenoplectus and Schoenoplectiella. Using more than a third of Fuireneae s.l. diversity, our phylogenomic analyses strongly support six genera and four major Fuireneae s.l. clades that we recognize as tribes: Bolboschoeneae stat.nov., Fuireneae s.s., Schoenoplecteae, and Pseudoschoeneae tr. nov. These results are consistent with morphological, micromorphological (nutlet epidermal cell shape), and embryo differences detected for each tribe. At the generic level, most sub-Saharan African perennials currently treated in Schoenoplectus are transferred to Schoenoplectiella. Our targeted sequencing results show that these species are nested in Schoenoplectiella, and their treatment here is consistent with micromorphological and embryo characters shared by all Schoenoplectiella species. Keys to recognized tribes and genera are provided.

靶向测序支持形态学和胚胎特征解析莎草科Fuireneae sl的分类

基于 Sanger 序列的分子系统发育研究表明，莎草科植物 Fuireneae sl 是并系的。然而，这些研究中的分类抽样很差，拓扑结构不一致，对树木主干的支持很弱。此外，不确定性仍然围绕Schoenoplectiella的形态限制，该属主要是小型两性一年生植物，最近与Schoenoplectus分离. 因此，尽管分子分析有充分的证据表明 Fuireneae sl 可能由两到四个部落谱系组成，但尚未进行分类学变化。在这里，我们使用被子植物 353 富集面板进行靶向测序，以 (i) 阐明 Fuireneae sl 与相关部落 Abildgaardieae、Eleocharideae 和 Cypereae 的关系；(ii) 定义 Fuireneae ss 的限制，以及 (iii) 测试 Fuireneae sl 属的单系性，重点是Schoenoplectus和Schoenoplectiella. 使用超过三分之一的 Fuireneae sl 多样性，我们的系统发育分析强烈支持我们认为是部落的六个属和四个主要的 Fuireneae sl 进化枝：Bolboschoeneae stat.nov.、Fuireneae ss、Schoenoplecteae 和 Pseudoschoeneae tr。十一月 这些结果与每个部落检测到的形态学、微形态学（坚果表皮细胞形状）和胚胎差异一致。在通用层面，目前在Schoenoplectus中处理的大多数撒哈拉以南非洲多年生植物被转移到Schoenoplectiella。我们的靶向测序结果表明，这些物种嵌套在Schoenoplectiella 中，它们在这里的处理与所有Schoenoplectiella共有的微形态和胚胎特征一致。物种。提供了公认的部落和属的钥匙。
