湖南参属的归并及亚洲楤木属(五加科)的一个新种和一些名称的变更

分子与形态证据表明湖南参 (HunaniopanaxhypoglaucusC .J.Qi&T .R .Cao)起源于木属 (AraliaL .) ,湖南参的近缘种为寄生五叶参 (Araliaparasitica)和轮伞五叶参 (Araliaverticillata) ,形态证据支持湖南参为轮伞五叶参的姐妹种 ,此 2种具轮伞花序这一共衍征。为了保证木属的单系性 ,现将湖南参并入木属 ,并作如下新组合 :Araliahypoglauca (C .J .Qi&T .R .Cao)J.Wen&Y .F .Deng .本文报道了湖南参在广西的新分布。目前的形态学和分子数据均不支持早先提出的湖南参与树参属 (Dendropanax)的近缘关系。本文亦报道了木属的 1新种、 2新种组合和 1个新名称 :AraliashangianaJ .Wen .sp .nov .(向氏五叶参 ,新种 ) ;Araliaglabrifoliolata (C .B .Shang)J .Wen .comb .nov . (光叶五叶参 ,新组合 ) ;Araliastellata (King)J.Wen ,comb .nov . (星毛羽叶参 ,新组合 )和AraliadelavayiJ .Wen .nom .nov .(云南五叶参 ,新名称 )。

On Merging Hunaniopanax with Aralia (Araliaceae),with Description of a New Taxon and Additional Nomenclatural Changes in Asian Aralia

Molecular and morphological evidence suggests that the newly described Hunaniopanax hypoglaucus C. J. Qi & T. R. Cao is nested within Aralia L.Specifically Hunaniopanax is closely related to Aralia parasitica and A verticillata .Morphological data support its sister species relationship with A verticillata because the two taxa share a synapomorphy of verticillate pattern of inflorescence.To maintain the monophyly of Aralia, Hunaniopanax is herein merged with Aralia , and a new combination, Aralia hypoglauca (C. J. Qi & T. R. Cao) J. Wen & Y. F. Deng, is made. Aralia hypoglauca is also newly recorded from Guangxi, China in this study.The previously hypothesized close relationship of Hunaniopanax with Dendropanax Decne. & Planch. was refuted by our micromorphological examination as well as the DNA data. A new species, Aralia shangiana J. Wen, is herein described and two new combinations and a new name are also proposed: Aralia glabrifoliolata (C. B. Shang) J. Wen, comb. nov., A stellata (King) J. Wen,comb. nov., and A delavayi J. Wen, nom. nov.
