摘　　要：网檐南星(Arisaema utile Hook. f. ex Schott)是分布于青藏高原喜马拉雅山区以及云南西部高黎贡山和雪山山脉的天南星科植物,以小叶边缘红色而区别于其他种。在四川省九龙县东部大雪山南段大渡河流域的湾坝乡和洪坝乡发现有网檐南星的分布,描述了其生境的植被类型和伴生物种,并对其间断分布的原因进行了讨论。Arisaema utile Hook. f. ex Schott belongs to Araceae and is distributed in the Himalayan ranges of QinghaiTibet Plateau, Gaoligong Mountains and Xueshan Mountains in western Yunnan province. It is distinguished from other species by the red edge of its three leaflets. This paper recorded the new distribution of Arisaema utile in Wanba and Hongba township of Jiulong county, Sichuan province, which is in the south section of Great Snow Mountains and a tributary of Dadu River. The vegetation types and companion species in its habitats were described, and the reasons for its discontinuous distribution were discussed.
