A new species of the genus Ranunculus from Iran

Abstract

A new species of the genus Ranunculus named Ranunculus microflorus Pakravan (Ranunculaceae) from Iran is described and illustrated. The smooth fruit and erect stem differentiate it from R. repens L., the straight beak distinguishes it from R. caucasicus M.B., also the small flowers distinguish it from both species. Pollen grains were also studied and provided additional characters. The similarities between this species and other closely related species are also discussed.
