Abstract

Asarum mitoanum, a new species of Asarum from Goto Isls., the northwestern Kyushu District of Japan, is described and illustrated. This species is related to Asarum hexalobum(sect. Aschidasarum), especially to var. controversum in sharing the calyx-tube constricted at the throat and tessellated with longitudinal and transverse ridges on inner surface, the calyx-lobe raised rugosely at base, the style which has no exserted longer stylar-protuberance on its dorsal part, and the broadly ovate to ovate leaves. However, the new species is clearly distinguished from A. hexalobum by having the characteristic trapeziform-urceolate calyx-tube, stigma located extrorsely near the top of style, half-inferior ovary and stamens reduced to half in number.
