【Abstract】 A new species of the genus Lysimachia, L. dextrorsiflora X. P. Zhang, X. H. Guo & J. W. Shao, is described and illustrated. This species, occurring in Anhui and Fujian provinces of China, is similar to L. christinae Hance in the prostrate stem, opposite leaves, yellow flowers born singly in leaf axils, but differs by having corolla lobes contorted towards the right and imbricate in the bud from a top view, the pedicel usually longer than the subtending leaves, and the flowering time from early April to early May. In L. christinae, the corolla lobes are contorted towards the left from a top view, the pedicels are usually shorter than the subtending leaves, and the flowering time from early May to early June.更多还原
