摘要	A new species, Potentilla polyphylloides H. Ikeda & H. Ohba. is described and illustrated. It is assigned to section Leptostylae by having an herbaceous habit. slender or fusiform styles. auricles of stipules (of banal leaves situated at adaxial side of petioles, and flowering stems from axils of basal leaves. It resembles P. polyphylla Wallich ex Lehmann, but differ, by its glandular hairs on the lower surface of leaflets, pedicels, and the outside of episepals, as well as the occasional rooting at the axils of cauline leaves on the lower portion of flowering stems. Potentilla polyphylloides resembles P. fullens Cardot sharing the glandular hairs, but P. fullens differs in having nearly entire episepals that are shorter than the sepals, and longer styles nearly twice as long as the ovaries. Potentilla polyphylloides has a chromosome number of 2n = 42, while that of P. polyphylla and P. fallens is 2n = 28.
