Boissier (Fl. Or. 5: 188. 1882) and Sealy (in Hooker’s Icones Plantarum 39(1&2): 185-190. 1980) have accepted Fritillaria karelinii (Fischer ex D. Don) Baker and have reduced Fritillaria gibbosa Boiss. to synonymy. Lozina-Lozinskaya in V. L. Komarov, Fl. USSR 4: 296-298. 1968 (English transl.) has placed both the species in the genus Rhinopetalum, which is now regarded as a section of Fritillaria. As Fritillaria karelinii has wingless capsule whereas Fritillaria gibbosa has winged capsule, the two taxa are being treated as separate species.
