In view of the forthcoming review of Turkish irises for Resimli Türkiye Florası (The Illustrated Flora of Turkey), nineteen names are typified or nomenclatural remarks are provided in the present report. Lectotypes are designated for Iris aschersonii, I. attica, I. bornmuelleri, I. purpureobractea (a taxonomic synonym of I. junonia), I. reticulata var. cyanea, I. reticulata var. sophenensis, I. suaveolens and I. taochia. The second-step lectotypification is made for I. histrio. Neotypes are designated for the names I. histrioides, I. junonia, I. masiae and I. reticulata var. histrioides; epitype, for the name I. reticulata var. sophenensis. For the previously typified names, I. bakeriana, I. musulmanica and I. reticulata, lectotypes are given. The lectotypes for I. histrio var. aintabensis, I. schachtii, and Xiphion danfordiae and the authorship for I. histrioides, are corrected. Images are provided for eight specimens selected as types that are not available online. Notes on distribution in Turkey are provided for all the accepted taxa.
