Morphological characterizations of genera in Cyperaceae tribe Abildgaardieae have been highly problematic and the subject of much debate. Earlier molecular phylogenetic studies based on Sanger sequencing and a limited sampling have indicated that several generic circumscriptions are not monophyletic. Here, we provide the first phylogenetic hypothesis for Abildgaardieae using targeted sequencing data obtained with the Angiosperms353 enrichment panel for 50 species. We test whether recent taxonomic decisions made based on Sanger sequencing data are validated by our targeted sequencing data. Our results support subsuming the small African genus Nemum into the large genus Bulbostylis and subsuming the monotypic genus Crosslandia into the diverse genus Fimbristylis. Also, our results support the recent publication of the new genus Zulustylis for two African species previously placed in Fimbristylis. Furthermore, we investigate the phylogenetic placement of recently described tropical Australian endemic species of Actinoschoenus, which are recognized here as the new morphologically cryptic genus Scleroschoenus. Based on our phylogenetic hypothesis and supported by morphological data, we recognize the genus Abildgaardia. The placement in Abildgaardieae of two monotypic genera Nelmesia and Trichoschoenus, only known from the type collections from the Democratic Republic of Congo and Madagascar, respectively, are also discussed. New combinations and lectotypifications are made in Abildgaardia, Actinoschoenus, Arthrostylis and Scleroschoenus.

使用靶向测序解决莎草科部落Abildgaardieae中的通用限制

莎草科中的属的形态学特征存在很大的问题，并且是许多争论的主题。较早的基于Sanger测序和有限采样的分子系统发育研究表明，几种通用限制不是单系统的。在这里，我们使用被子植物353富集小组获得的针对50种物种的靶向测序数据，为Abildgaardieae提供了第一个系统发育假说。我们测试了基于Sanger测序数据做出的近期分类学决策是否已通过我们的目标测序数据验证。我们的研究结果支持将非洲的小型Nemum归入Bulbostylis大的属，并将单型Crosslandia归入多样化的属。Fimbristylis。同样，我们的研究结果支持了祖鲁斯蒂利斯新属的最新发表，该祖鲁斯蒂利斯属是先前放置在Fimbristylis中的两个非洲物种的。此外，我们调查的最近描述热带澳大利亚特有的物种的进化位置Actinoschoenus，这是这里公认的新形态神秘属Scleroschoenus。基于我们的系统发育假说并得到形态学数据的支持，我们认识到了阿比尔德贾第虫属。两个单型属Nelmesia和Trichoschoenus在Abildgaardieae中的位置还讨论了，分别仅从刚果民主共和国和马达加斯加的类型收藏中得知。新的组合和lectotypifications是在由Abildgaardia，Actinoschoenus，Arthrostylis和Scleroschoenus。
