    Abstract

    Oxalis shibeishanensis Huan C. Wang & Y. Tian (Oxalidaceae), belonging to O. subsect. Oxalis, is described and illustrated as a new species endemic to Yunnan, Southwest China. It is most similar to O. obtriangulata, but clearly differs from the latter by its 1.5–3 cm long, 3–9 cm wide leaflets with broadly cuneate base and not emarginate apex, 2-flowered inflorescences, narrowly ovate to broadly lanceolate sepals, and the petals being bifid at the apex.
