The classification of Oxalis subsect. Oxalis (Oxalidaceae) is revised based on phylogenetic, cytological and morphological evidence. For the flora of Japan, one new species and one new variety are described, and five new combinations are proposed. The new species, O. nipponica, resembles O. griffithii, but is distinguished by its unique phylogeny, larger genome and distribution. Oxalis nipponica is subdivided into two subspecies, nipponica and kantoensis based on phylogeny and fruit length. Subsp. kantoensis is further divided into two varieties based on ploidy level, length of the fruit and seeds and habitat. While diploids correspond to var. kantoensis, the tetraploids correspond to the newly described var. alpigena. Variety alpigena resembles O. acetosella and has been confused with it. Fourteen taxa, including one hybrid, are recognized in subsect. Oxalis.

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.

The taxonomic treatment of Arisaema (Araceae) in China in volume 23 of the Flora of China (FOC) in 2010 recognized 78 species in 12 sections. The circumscription of the sections was revised by Murata in 2011 and the names of the sections were reviewed more recently by Murata et al. in 2013. In the FOC the circumscription of some species was changed drastically and four new species were described. Notes on the treatment in the FOC are given, based on recent cytological and molecular data, according to the sections recognized by Murata et al. in 2013.
