 note = {Ixeris dentata subsp. nipponica is a vulnerable species which grows only some limited seaboard bluffs in Kashiwazaki. Ixeris dentata is a complex species composed of some subspecies, varieties and forms. Genetic polymorphism among four kinds of this species, viz., subsp. nipponica, var. albiflora, var. albiflora f. amplifolia and the type species was investigated by PCR-RAPD analysis. Genetic distances between every pair of collected samples were calculated according to shared polymorphic bands of RAPD. Each kind was placed as a separate cluster from others on the phylogenetic tree based on genetic distances. And two clusters of subsp. nipponica and var. albiflora f. amplifolia were conected first, then the cluster of var. albiflora joined together. It was indicated that subsp. nipponica is related most closely to var. albiflora f. amplifolia among the examined four kinds of Ixeris dentata and the type species is less related to other three.},
