A new variety, Aristolochia kaempferi Willd. var. laevipes Watan.-Toma & Ohi-Toma (Aristolochiaceae), is described. The variety is distinguished from var. kaempferi by having glabrous pedicels. This new variety is disjunctly distributed in the Ise-Shima region of the Kii Peninsula and the northeastern part of the Owari region of central Honshu, Japan. Moreover, we newly confirmed the presence of A. kaempferi var. kaempferi in the central part of the Kii Peninsula and the Owari region based on flowering individuals in natural populations and in cultivation. Aristolochia kaempferi var. kaempferi and A. tanzawana were in proximity with A. kaempferi var. laevipes in the Owari region.
