Fritillaria nevzatcaglari Yıldırım & Tekşen (Liliaceae) is described and illustrated as a new species from Turkey. It morphologically resembles F. ozdemir-elmasii, F. bithynica and F. elwesii, but differs from them by several characters, the most distinct one being a pale purple outer surface of the perigon. Due to human activities and grazing pressure in the are where F. nevzatcaglari grows, we assess its conservation status as critically endangered (CR).
