Abstract

Abstract. Golden everlasting paper daisies in the genus Xerochrysum Tzvelev are iconic Australian native plants grown worldwide. The X. bracteatum species complex has been regarded as taxonomically confusing and in need of revision for over 60 years. We applied morphological and molecular analyses to delimit species, detect common ancestry among populations, and identify putative hybrids in the genus Xerochrysum (Asteraceae: Gnaphalieae). Multiple lines of evidence provided strong support for the recognition of new taxa. Here we describe the following 11 new species: X. andrewiae T.L.Collins & J.J.Bruhl, X. berarngutta T.L.Collins & I.Telford, X. copelandii J.J.Bruhl & I.Telford, X. frutescens J.J.Bruhl & I.Telford, X. gudang T.L.Collins & J.J.Bruhl, X. hispidum T.L.Collins & I.Telford, X. macsweeneyorum T.L.Collins, X. murapan T.L.Collins & I.Telford, X. neoanglicum J.J.Bruhl & I.Telford, X. strictum T.L.Collins, and X. wilsonii T.L.Collins, reinstate Helichrysum banksii A.Cunn. ex DC. (as X. banksii (A.Cunn. ex DC.) T.L.Collins & I.Telford), lectotypify X. banksii and X. papillosum (Labill.) R.J.Bayer, and recircumscribe X. bicolor (Lindl.) R.J.Bayer to include X. halmaturorum Paul G.Wilson and some populations of X. bracteatum sens. lat. from mainland South Australia and Victoria. We also provide revised descriptions of all taxa in the genus, their conservation status, a dichotomous key, tables distinguishing closely related taxa and distribution maps.

那座山上有金子!菊科干菊花的形态和分子划分;Gnaphalieae)，揭示了许多新的分类群

摘要Xerochrysum Tzvelev属的金色永恒纸雏菊是世界各地生长的标志性澳大利亚本土植物。60多年来，苞片X.物种复合体一直被认为在分类学上令人困惑，需要修订。我们应用形态学和分子分析来界定物种，检测种群之间的共同祖先，并鉴定Xerochrysum属（菊科：Gnaphalieae）的假定杂交种。多条证据线为新分类群的识别提供了有力的支持。在这里，我们描述了以下11个新物种：X.andrewiae T.L.Collins&J.J.Bruhl，X.berarngutta T.L.Collins&I.Telford，X.copelandii J.J.Bruhl&I.Tel福德，X.frutescens J.J.Bruhn&I.Telford，X.gudang T.L.Collings&J.J.J.Bruhn，X.hispidum T.L.Collinst&I.Telford，X.macsweeneyorum T.L.Colliins，X.murapan T.L.Collinds&I.Telfford，X.neongicum J.Bruhl&I.Telford，和X.wilsonii T.L.Collins，恢复Helichrysum banksii A.Cunn.ex DC。（如X.banksii（A.Cun.ex DC.）T.L.Collins和I.Telford），选择X.banksiii和X.papillosum（Labill.）R.J.Bayer，以及再循环记录X.bicolor（Lindl.）R.J.拜耳，包括X.halmatorum Paul G.Wilson和一些来自南澳大利亚大陆和维多利亚州的X.bracketatum sens.lat.种群。我们还提供了该属所有分类群的修订描述、它们的保护状况、二分键、区分密切相关分类群的表格和分布图。

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.
