A new species of Onosma L. (Boraginaceae: Lithospermeae), from the Hakkari province of eastern

Turkey, is described and illustrated. The new species is endemic and distributed in a narrow area in

the Sat Mountains. Taxonomically the closest relative of Onosma satensis sp. nov. is O. polioxantha

Rech. f. which also occurs in Turkey. In addition, it is primarily distinguished from O. polioxantha by

its navicular leaves, longer and reticulate cauline leaves, longer pedicels and calyx, longer and densely

patent short setulose outside, reticulate corolla and bigger nutlets. The geographical distributions and

map, detailed photographs, habitat description, vernacular name, an IUCN conservation status and

identification key for O. satensis sp. nov. and O. polioxantha were also provided. Nutlets and pollen

micrographs of O. satensis sp. nov. are presented using scanning electron microscopy.
