Abstract

Studies of African material of the tribe Paniceae (Poaceae) resulted in the transfer of 12 species from Panicum, the description of a new species, and the conclusion that the genus Trichanthecium now consists of 52 species. The new Trichanthecium delimitation was confirmed by phylogenetic studies based on chloroplast ndhF and rbcL sequences. Morphological and anatomical characters are discussed within their pylogenetic context. A new species is described: T. marunguensis. Lectotypes are designated for Panicum aequinerve, P. calvum, P. chionachne, P. hochstetteri var. glaberrimum, P. inaequilatum, P. lepidum, P. mokaense, and P. wiehei. The following new combinations are proposed: T. acrotrichum, T. aequinerve, T. calvum, T. chionachne, T. delicatulum, T. eickii, T. hochstetteri, T. inaequilatum, T. perrieri, T. pusillum, T. striatissimum, and T. wiehei. Full synonymies, descriptions, distribution and habitat information, citation of all specimens and a key to the Old World species of the genus are provided; seven species are illustrated.

Trichanthecium (Poaceae: Panicoideae: Paniceae) 的旧大陆种，包括刚果民主共和国的一个新种

通过对非洲野豌豆科（Poaceae）的材料进行研究，从豌豆中分离出 12 个物种，描述了一个新物种，并得出 Trichanthecium 属现在由 52 个物种组成的结论。基于叶绿体 ndhF 和 rbcL 序列的系统发育研究证实了新的 Trichanthecium 定界。在幽门发生学背景下讨论了形态学和解剖学特征。描述了一个新物种：T. marunguensis。p. hochstetteri var. glaberrimum, P. inaequilatum, P. lepidum, P. mokaense, and P. wiehei.提出了以下新组合：acrotrichum、T. aequinerve、T. calvum、T. chionachne、T. delicatulum、T. eickii、T. hochstetteri、T. inaequilatum、T. perrieri、T. pusillum、T. striatissimum 和 T. wiehei。提供了完整的同义词、描述、分布和栖息地信息、所有标本的引文以及该属旧大陆种的检索表；其中 7 个种配有插图。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
