摘　　要：本文将在形态学观察以及统计学分析的基础上,研究洪雅十大功劳与其关键节点的物种的区别并确定洪雅十大功劳属的新种地位,结果表明洪雅十大功劳作为一新种,可通过锯齿数目、小叶对数、顶生小叶长度与阔叶十大功劳相鉴别开;通过小叶对数、第一个节间距与小果十大功劳相鉴别开;通过小叶宽度、锯齿数目、顶生小叶长度、第一个节间距与细齿十大功劳相鉴别开;通过小叶宽度、顶生小叶长度、第一个节间距与宜章十大功劳相鉴别开;通过小叶宽度、锯齿数目、小叶对数、顶生小叶长度、第一个节间距与峨眉十大功劳相鉴别开。因此证实了洪雅十大功劳的新种地位。This article will be on the basis of morphologic observation and statistical analysis, studies Mahoniahongyaensis of credit and its key node and determine the difference between a Mahoniahongyaensi of the genus credit status, the results show that Mahoniahongyaensi credit as a new species.We can through the sawtooth number, lobules logarithm, apical length to identification of M.bealei;through the lobular logarithm, the spacing between the first section to identification of M.bodinieri;through the leaf width, the number of serrated teeth, the length of terminal lobule, the space between the first node to identification of M.leptodonta;through the width of lobule, length of terminal lobule, the space between the first section to identification of M.cardiophylla;through the leaf width, serrated number, lobule logarithm, length of terminal lobule, spacing of the first node to identification of M.polydonta. Thus confirmed Mahoniahongyaensiis a new species.
