摘要

Aristolochia kaempferi Willd. is widely distributed in Honshu (Kanto and westwards), Shikoku and Kyushu in Japan, and shows large morphological variation. Within the species, several infraspecific taxa have been recognized, but only one variety, var.tanzawana Kigawa, is recently accepted based on the spreading hairs on the nerves of the abaxial side of leaves. Based on an extensive investigation through the whole geographical range of A. kaempferi, we found the differences in the flower morphology and the segregation of distribution between var. kaempferi and var. tanzawana. Here, A. tanzawana (Kigawa) Watanabe-Toma & Ohi-Toma is newly recognized in the rank of species.
