Abstract: Molecular and morphological evidence suggests that the newly described Hunaniopanax hypo-glaucus C.J.QI & T.R.Cao is nested within Aralia L.Specifically Hunaniopanax is closely related to Aralia parasitica and A.uerticllata.Morphological data support its sister species relationship with A.uer-ticillata 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 comination,Aralia hypo-glauca(c.J,Qi&T.R.Caao)J,Wen & Y.F.Deng ,is made .Aralia hypoglauca is also newly recorded from Guangxi,China in thes study.The previously hypothesized close relationship of Hunanuio-panax with Dendropanax Decne,& planch.was refuted by our micronorphological 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.st-ellata(king )J.Wen,comd.nov.,and A.delauayi J. Wen nom .nov

Key words: Hunaniopanax, Aralia glabrifoliolata, Aralia stellata.
