For the purpose of providing a genetic basement for the systematics of Arisaema serratum group, allozyme differentiation among 13 populations of II species within Arisaema serratum group and their allies(A. tosaense, A. naximowiczii, A. undulatifolium, A. iyoanum and A. nikoense)are examined using starch gel electrophrasis. For comparison, well differentiated temperate species(A. heterocephalum, A. thunbergii, A. heterophyllum and A. tortuosum)and species of a tropical group, section Fimbriata, (A. filiforme, A. inclusum, A. laminatum and A. grapsospadix)are also investigated. As a result of investigation, genetic distance between the population of different "species" was found to be very low in A. serratum group(D = below 0.05). It is less than the value between conspecific populations of A. thnubergii(D = below 0.44)and of A. filiforme(below 0.14). Consequently, the "species" of A. serratum group are considered to be in the early stage of speciation, which seems to have been initiated quite recently, probably through the late grader period on the complicated topology of Japanese Islands.

为给锯缘天南星组的系统学研究提供遗传基础，对锯缘天南星组II种及其近缘种（A.serratum）13个居群的等位酶进行了比较研究。tosaense，A. naximowiczii、黑腹滨藜A. undulatifolium，A. Iyoanum和A.用淀粉凝胶电泳法检测了这些蛋白质的含量。作为比较，分化良好的温带种（A。heterocephalum，A. thunbertus，A. heterophyllum和A. tortuosum）和一个热带类群，流苏组（A. filiforme、A. inclusum，A. laminatum和A. grapsospadix）也进行了研究。调查结果表明，不同“种”的群体间的遗传距离很小。锯齿组（D = 0.05以下）。它小于A. thnuberculosis（D = 0.44以下）和A.丝状（低于0.14）。因此，A. serratum组被认为是在早期阶段的物种形成，这似乎是最近开始的，可能是通过后期等级时期的复杂的地形日本岛屿。
