摘　　要：本文报道了在云南高黎贡山地区发现的芸香科新记录变种——刺异叶花椒。其属于异叶花椒的一个变种,最显著的鉴别特征为小叶边缘有锯齿或针刺;灌木或小乔木,生长于海拔300~2400 m的针阔混交林林缘或山坡灌丛中;标本采集地所发现的刺异叶花椒为一个稳定种群,由200余株植株组成;通过标本查询鉴别证明此变种在云南未见标本记录,这一新记录变种的发现,使云南花椒属植物由6个种3个变种增加为6个种4个变种,再一次佐证了高黎贡山的生物多样性丰富。This paper reports a new record variety of Rutaceae found in Gaoligong Mountains of Yunnan Proveince.Zanthoxylum dimorphophyllum var.spinifolium is a variant of Zanthoxylum subgen.The most distinctive feature is the presence of serrations orines on the leaf margins.It as a shrub or small tree distributed in the mixed coniferous and broad-leaves forest in hillside;the population of Z.imorphophyllum var.spinifolium found in the collection area is stable,with more than 200 plants.By checking and identifying the plant specimens,we have identified it as a new variant which has increased the number of Zanthoxylum species in Yunnan from 6 species and 3 varieties to 6 species and 4 varieties.The results further demonstrated the rich biodiversity of the Gaoligong Mountains.
