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 previously healthy 58-year-old man was admitted for muscle pain and weakness [manual muscle testing (MMT) of 4/4 for upper and lower limbs]. We detected elevated levels of inflammatory makers and PR3-anti-neutrophil cytoplasmic antibody (ANCA). Subsequently, the muscle weakness rapidly progressed to an MMT of 2 for all limbs. Magnetic resonance imaging indicated muscle edema, and the creatine kinase (CK) level increased to 29,998 U/L. Methylprednisolone (mPSL) and cyclophosphamide pulse therapy improved the patient symptoms. MMT recovered to 4 for all limbs. A muscle biopsy showed degenerated muscle fibers surrounded by neutrophil-predominant infiltration. In addition, lamina elastic breakdown and fibrinoid necrosis of arterioles were observed. A final diagnosis of microscopic polyangiitis (MPA) limited to the muscles was made.
