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

ABSTRACT 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.ABSTRACT 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.
