Reichenbach published Ranunculus binatus in his Flora Germanica Excursoria in 1832, based on a specimen collected by Welden in Transylvania, Romania, and attributed the name to Kitaibel. Since then, the identity of R. binatus has been a focus of discussion by Schur, Janka, Schiller, Jasiewicz and further botanists, in particular since Schiller considered R. binatus a corner stone in the evolution of the R. auricomus complex. To clarify the concept of R. binatus and settle the application of the name, it is here typified. Because no specimen used with certainty by Reichenbach appears to be extant, a well preserved specimen in the herbarium Kitaibelianum, Budapest, identified by Kitaibel himself as R. binatus, collected by Genersich in northern Slovakia and morphologically agreeing well with the original description, is designated as the neotype of the name R. binatus. © 2011 BGBM Berlin-Dahlem.

Ranunculus auricomus complex in Northern Italy has been classified and analyzed morphologically. Plants close to Ranunculus cassubicus are attributed to R. cassubicifolius. In addition to species already published by Pignatti and other authors, the following species are described: Ranunculus fraelensis, R. mediogracilis, R. cochlearifer, R. plavensis, R. baldensis, R. abbaianus, R. pedemontanus and R. poldinii.

Ranunculus auricomus s.l. (Ranunculaceae) has been found only a few times in Greece since its first finding there by Haussknecht in 1893, all records coming from the area of the Katara pass in the Pindos mountains. All populations seem to be identical, and the Greek plants are described and named here as R. pindicola sp. nov. The new species is geographically isolated; the nearest localities of other members of the R. auricomus complex are in the Rila mountains of Bulgaria and the Sila mountains of Calabria in S Italy. According to present knowledge, R. pindicola is a rare endemic species of C Greece. It is threatened by eutrophication or abandonment of its meadow sites. © 2015 BGBM Berlin.

The Ranunculus auricomus complex in Central and Southern Italy has been classified and analyzed morphologically. Corresponding to a known genetic variation, a high morphological variability of Ranunculus marsicus was found leading to segregation of two new varieties var. approximans and var. incisior. In addition to species already published by Pignatti and other authors, the following taxa are described and depicted: Ranunculus bariscianus, R. multidens, and R. pedrottii from the Central Apennines, and R. bovii, a new endemic of the Aosta Valley. R. boreoapenninus had been found in the Tuscany but has not been confirmed recently. R. silanus, a completely geographically isolated member of the R. auricomus complex from Calabria is still present. The amount of knowledge on the Ranunculus auricomus complex in Italy may serve as a basis for further research; this should preferentially be of a biomolecular kind to disclose the genetic relations and the evolution of the taxa concerned.

A new species of the Ranunculus auricomus complex, Ranunculus farraensis sp. nov. is described and depicted. Specimens of it were detected at the Herbarium Dresde (DR), in material collected in 1955 by C. Zirnich. Its actual occurrence has been recently confirmed in the Farra mountains, in Gorizia province. Due to small population size and continuing eutrophication of the remaining forest, R. farraensis is at risk of extinction. © 2016 Dipartimento di Biologia, Università di Firenze
