Hedysarum pseudomacranthum is described here as a new species to science. It is endemic to the Talesh Mountains, northwestern Iran. The species appears to be most closely related to H. macranthum, but differs from it in having different leaflet shape and dimensions, different color of the corolla, and longer keel’s claw. The distribution map as well as the picture from the holotype habit and the flower parts of the new species are presented here.
