The typification of Ranunculus bullatus L. is discussed and a lectotype and epitype chosen which maintain usage of the name in the sense of subsp. bullatus. Ranunculus bullatus subsp. cytheraeus (Halácsy) Vierh. is recognized at species rank, and the combination R. cytheraeus (Halácsy) Baldini is made to accommodate it. Both taxa are described and illustrated. The names R. bullatus L. var. cuneifolius Coustur. & Gand., R. bullatus L. var. cyrenaicus Pamp., R. bullatus L. var. ovatus Freyn, R. bullatus L. var. prolifer Gennari, R. semicalvus Jord. & Fourr. and Ionosmanthus plantagineus Jord. & Fourr. are also typified.
