抄録

In connection with a revision of the Japanese species of Arisaema, the length of the peduncle relation to the length of the petiole, and the number of ovules per ovary were extensively examined in most of the Japanese species and were re-evaluated as critical taxonomic characters. Mainly on the basis of those characters, the taxonomic status of A. kishidae MAKINO var. minus SERIZAWA and the relationship between A. kishidae and A. undulatifolium NAKAI were reconsidered. 1. The ranges of variation in the length of the peduncle and the petiole of the Japanese species are shown in scatter diagrams in Figures 2 and 3. The length of the peduncle in A. heterophyllum BLUME (Fig. 2A) and A. undulatifolium NAKAI (Fig.2B) is mostly longer than the petiole. In A. ogatae KOIDZ. (Fig. 3L), A. sazensoo MAKINO (Fig. 3Q), A. ovale NAKAI (Fig. 3R), A. iyoanum MAKINO subsp. iyoanum (Fig. 3S), A. seppikoense KITAMURA(Fig. 3U), A kuratae SERIZAWA (Fig. 3V) and A. thunbergii BLUME and A. kiushianum MAKINO (Fig 3W) the peduncle is always shorter than the petiole. Two modes of sexual differentiation are correlated with the length of the peduncle. In A. undulatifolium (Fig. 2B), A. yamatense NAKAI (Fig. 2C), A. abei SERIZAWA (Fig. 2D), A. maximowiczii NAKAI and A. tashiroi KITAMURA (Fig. 2E), A monophyllum NAKAI (Fig. 2F) A. tosaense MAKINO (Fig. 2G) and A. iyoanum subsp. nakaianum (OHBA) OHASHI et J. MURATA (Fig. 3T) the peduncle is generally longer in female plants than in male plants, but in A. sikokianum FR. et SAV. (Fig 3P), A. negishii MAKINO (Fig. 3N) and A. heterocephalum KOIDZ. (Fig. 3M) the peduncle is shorter in female than in male plants. In A. kishidae (Fig. 3O) the range of variation widely overlaps between male and female, but the mode of the differentiation is similar to that of the latters : The peduncle is nearly as long as the petiole in male plants of A. kishidae but, in female plants, usually shorter than the petiole.
