Abstract

A new genus, Anthelepis R.L.Barrett, K.L.Wilson & J.J.Bruhl, is described for four Cyperaceae species from mainly tropical areas of South-East Asia, New Caledonia and Australia. The relationships of the three previously described species have been much-debated. In recent decades, they have most commonly been placed in either Schoenus L. or Tricostularia Nees ex Lehm., but molecular phylogenetic data have demonstrated that they are not closely related to either genus and a new generic name is required. The following three new combinations are made: Anthelepis guillauminii (Kük.) R.L.Barrett, K.L.Wilson & J.J.Bruhl (based on Schoenus guillauminii Kük.), A. paludosa (R.Br.) R.L.Barrett, K.L.Wilson & J.J.Bruhl (based on Chaetospora paludosa R.Br.) and A. undulata (Thwaites) R.L.Barrett, K.L.Wilson & J.J.Bruhl (based on Cladium undulatum Thwaites). One new species, Anthelepis clarksonii R.L.Barrett, K.L.Wilson & J.J.Bruhl, is described from northern Queensland, Australia, as distinct from A. undulata. Full descriptions, illustrations and a key to species are provided. All species are confirmed as having C3 anatomy.

Anthlepis，澳大利亚、新喀里多尼亚和东南亚莎草科四个主要热带物种的一个新属

描述了四种莎草科植物的一个新属，Anthlepis R.L.Barrett，K.L.Wilson和J.J.Bruhl，主要分布在东南亚、新喀里多尼亚和澳大利亚的热带地区。之前描述的三个物种之间的关系一直备受争议。近几十年来，它们最常见于Schoenus L.或Tricostularia Nees ex Lehm。，但分子系统发育数据表明，它们与任何一个属都没有密切关系，需要一个新的属名。以下三个新组合被制成：Anthlepis guillauminii（KüK.）R.L.Barrett，K.L.Wilson和J.J.Bruhl（基于Schoenus guillauminii KüK），A.paludosa（R.Br.）R.L.巴雷特，K.L.威尔逊和J.J.布鲁尔（基于Chaetospora paludosaR.Br。一个新的物种，Anthlepis clarksonii R.L.Barrett，K.L.Wilson和J.J.Bruhl，被描述为来自澳大利亚昆士兰北部，与A.undulata不同。提供了完整的描述、插图和物种钥匙。所有物种都被证实具有C3解剖结构。

期刊介绍： Australian Systematic Botany is an international journal devoted to the systematics, taxonomy, and related aspects of biogeography and evolution of all algae, fungi and plants, including fossils. Descriptive taxonomic papers should normally constitute a comprehensive treatment of a group. Short papers on individual species and nomenclatural papers must contain significant new information of broader interest to be considered. The prestigious L.A.S. Johnson Review Series is published. Other review articles will also be considered. All papers are peer reviewed. Australian Systematic Botany is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science.
