Abstract
A new species, Dionysia persica Majidi & Alipour (Primulaceae) from Shiraz, Iran, is described and illustrated. It is similar to Dionysia bokharii but differs in leaves with usually deeply lobed and pinnately veined with weakly sclerified veins, much shorter calyx and corolla tube, smaller corolla limb with narrower and more distinctly emarginate lobes, and fewer ovules and seeds. Unlike all other Iranian Dionysia species, it is homostylous. A detailed description, photographs, geographical distribution, conservation assessment, and taxonomic comments on the new species are presented.
