Abstract

Abstract. We present a phylogeny based on four DNA molecular markers (rps16–trnK spacer, rps16 intron, rpl32–trnL spacer and ITS) concentrating on species of Eragrostis Wolf in Australia. Two Australian radiations are shown within Eragrostis, one being centred in the arid zone and one in the monsoon tropics. The genus is paraphyletic, with species of Cladoraphis Franch., Ectrosia R.Br., Harpachne Hochst. ex A.Rich., Heterachne Benth., Neeragrostis Bush, Planichloa B.K.Simon, Psammagrostis C.A.Gardner & C.E.Hubb. and Stiburus Stapf together forming a well supported clade mixed with Eragrostis species. The molecular results are consistent with recognition of an expanded Eragrostis and we make the following new combinations for Australian taxa: Eragrostis agrostoides (Benth.) R.L.Barrett & P.M.Peterson, E. anomala (C.E.Hubb.) R.L.Barrett & P.M.Peterson, E. appressa (S.T.Blake) R.L.Barrett & P.M.Peterson, E. baileyi (C.E.Hubb.)

Eragrostis的分子系统发育（Poacee:Chloridoideae:Eragrostideae）：使澳大利亚的爱情草成为单系

摘要我们提出了一个基于四个DNA分子标记（rps16–trnK间隔子、rps16内含子、rpl32–trnL间隔子和ITS）的系统发育，这些标记集中在澳大利亚的Eragrostis Wolf物种上。Eragrostis内显示了两个澳大利亚辐射，一个集中在干旱区，一个在季风热带。该属为副系，种为枝形目。，Ectrosia R.Br.，Harpachine Hochst。前A.Rich.，Heterachne Benth。，Neeragrostis Bush、Planichloa B.K.Simon、Psammagrostis C.A.Gardner&C.E.Hubb.和Stiburus Stapf共同形成了一个与Eragrostis物种混合的分支。分子结果与对扩展Eragrostis的识别一致，我们为澳大利亚分类群做出了以下新组合：Eragrostisagrostoides（Benth.）R.L.Barrett和P.M.Peterson，E.anomala（C.E.Hubb.）R.L.巴雷特和P.M.彼得森，E.appressa（S.T.Blake）R.L.barett和P.M.Peterson，E.blakei（C.E.Hubb.）R.L.Barrett&P.M.Peterson，E.confusa，E.wiseana（C.A.Gardner&C.E.Hubb.）R.L.Barrett&P.M.Peterson和Sporobolus ramigerus（F.Muell.）P.M.Petersen，RomaschR.L.Barrett，并提出以下新名称：E.diversions R.L.Barrett&P.M.Peterson、E.lilliputiana R.L.Barret&P.M.彼得森和E.nightingaleae R.L.Barrette&P.M.Peter森。，E.anomala C.E.Hubb.、E.appressa S.T.Blake、E.baileyi C.E.Hubb.、E.blakei C.E.Hubb.、E.confusa C.E.Hubb、E.guliveri F.Muell、E.laxa S.T.Blanc、E.leporina R.Br、E.lepolina var.longiglumis C.E.Hubb.E.schultzii Benth。，E.schultzii var.annua C.E.Hubb.，E.spadicea R.Br.，澳大利亚甘油。，Heterachne guliveri Benth。，Heterachne guliveri var.major C.E.Hubb、Poa ramigera F.Muell和Psammagrostis wiseana C.A.Gardner&C.E.Hubb。

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.
