Perennial herbs, with trailing branches often rooting at the nodes (leafy runners), 3-foliolate long-petioled leaves and axillary slender-peduncled yellow perfect flowers. Calyx 5-parted, 5-bracteolate, the bractlets larger than the calyx-segments and alternating with them, dentate or incised, often regarded like those in Fragaria and Potcntilla as an exterior calyx. Petals 5, obovate. Stamens numerous. Pistils numerous, borne on a hemispheric receptacle which greatly enlarges but does not become pulpy in fruit. Achenes superficial on the receptacle. [In honor of A. N. Duchesne, French botanist.]

Two species, natives of southern Asia, the following typical.
