Research Abstract

Asarum section Bicornia (Aristolochiaceae) is composed of more than 8 taxa endemic to Japan. Morphologically, these taxa share a cup-shaped calyx-tube, a simply formulated lattice-like reticulation on a calyx-tube and a shorter stylar-protuberance, and thereby they have assigned to the same section and have appeared to be diversified in spreading from southwestern to eastern districts of Japan (Maekawa, 1953). In order to clarify the phylogenetic and biogeographical relationships of the above taxa we investigated molecular phylogeny, using DNA sequences from the chloroplast DNA region (trnL/F), the internal transcribed spacer (ITS) of nuclear ribosomal DNA, and ETS. In addition, morphological studies were carried out, since taxonomically there still remains unclear as to a few taxa. Although sequences of trnL/F, ITS-1 and ETS were found to be invariable and thus to be not useful for considering the phylogeneticrelationshipsamongthesetaxa, we determined the plants from the Suzuka mountain ranges to be specifically distinct. Moreover, we confirmed that the plants distributed from Hokuriku to Sanin Districts, which have been assigned to A.rigescens, were geographically differentiated into more than two local races or varieties.
