自19世纪初以来，人们就在非洲大陆收集淡水红藻。然而，这些收藏品数量稀少，地理位置有限。本研究旨在汇集文献，植物标本馆标本和新收集的标本，以提供一个更新的评估非洲大陆的淡水红藻多样性的重点是物种丰富的Batrachospermales的信息。对最近采集的标本进行了DNA序列数据和形态学观察。根据这些分析，提出了四个新的分类群：Kumanoa bouwmanii，Sheathia murpheyi，Sirodotia kennedyi和形式分类群'Chantransia azurea'。先前已发表了Kumanoa iriomotensis、Sirodotiaaff.huillensis和S.苏西卡通过这项研究，我们增加了Torularia atraas的序列数据，并为S.苏西卡总共有八个分类群具有序列数据，其中五个似乎是特有的。从我们对文献报道和植物标本馆标本的评估中，我们得出结论：Kumanoa，Sirodotia和Torularia经常被收集，并且在地理上相对广泛，存在两个或两个以上的物种。此外，植物群中还有Montagnia、Nothocladus、Paralemanea、Sheathia、Visia和Batrachospermum sectionGonimopropagulum。我们估计，14至19 batrachospermalean分类群可以被确认为非洲植物群，并与更多的研究，这个数字可以很容易地两倍或三倍的基础上，从其他研究充分的大陆已知的多样性。
Freshwater red algae have been collected on the African continent since the early 1800s. However, the collections have been sparse and geographically restricted. The present study sought to bring together information from the literature, herbarium specimens, and newly collected specimens to provide an updated assessment of the freshwater red algal diversity of the African continent with a focus on the species-rich Batrachospermales. DNA sequence data and morphological observations were conducted for recently collected specimens. From these analyses, four new taxa are proposed:Kumanoa bouwmanii, Sheathia murpheyi, Sirodotia kennedyi, and the form taxon ‘Chantransia azurea’. DNA sequence data had been previously published forKumanoa iriomotensis, Sirodotiaaff.huillensis, andS. suecica. With this study, we have added sequence data forTorularia atraas well as a second location forS. suecica. In total, there are eight taxa with sequence data, of which five appear to be endemic. From our assessment of literature reports and herbarium specimens, we conclude thatKumanoa, Sirodotia, andTorulariahave often been collected and are relatively geographically widespread with two or more species present. In addition,Montagnia, Nothocladus, Paralemanea, Sheathia, andVisiaas well asBatrachospermumsectionGonimopropagulumare represented in the flora. We estimate that 14 to 19 batrachospermalean taxa can be recognised for the African flora, and that with more study, that number could easily double or triple based on the diversity known from other well-studied continents.
