Euphorbia iranshahri (Euphorbiaceae), a new endemic species from Iran

During the joined study on recently collected specimens and herbarium sheets belonging to the genus Euphorbia (Euphorbiaceae), a new species, Euphorbia iranshahri Pahlevani, was reported and illustrated as endemic from the Zagros Mountains in Iran. This species is morphologically distinct from E. microsciadia Boiss. by possessing 6-8 rays and ray-leaves, subulate cyathia lobes longer than (or sometimes equal to) anthers, sharp-keeled capsules and smooth seeds.
