基于野外实地考察及文献梳理筛查,首次报道了中国五加科五加属一新记录种:太白大刺五加(Acanthopanax aspertus var.taibeiensis X.Q.Liu,H.Y.Choi,G.H.Lee et C.S.Yook),并提供详细形态特征图。该种形态上与刺五加[Acanthopanax senticosus(Rupr.Maxim.)Harms]和韩国特产植物大虾蛦五加(Acanthopanax aspertus var.koreanus Nakai)近似,但太白大刺五加叶柄末端轮生大刺,茎绿色且茎上无针状下向密生刺,3者容易区分。凭证标本保存于湖南中医药大学标本馆。

Based on field investigation,specimen examination and literature review,Acanthopanax aspertus var.taibeiensis X.Q.Liu,H.Y.Choi,G.H.Lee et C.S.Yook was reported as a new record of Araliaceae from Baoji Shaanxi of China.The description of its characteristics and specimen pictures have been provided.The shape of this species is similar to Acanthopanax senticosus(Rupr.Maxim.)Harms and Acanthopanax aspertus var.koreanus Nakai,However,the former has large thorns whorled at the end of the petiole,green stems,and no needle like downward dense spines on the stems,making it easy to distinguish between the three.The voucher specimens are deposited in the herbarium of Hunan University of Chinese Medicine.
