Nomenclatural Synopsis, Revised Distribution and Conservation Status of Ranunculus gracilis (Ranunculaceae) in Italy.

Ranuculus gracilis is endemic to the SE Euro-Mediterranean area and its presence in Italy is controversial. Based on analysis of the relevant literature, field surveys and examination of herbarium specimens, a revised distribution of this species in Italy is presented and its conservation status is assessed. Ranunculus agerii , described by Antonio Bertoloni from Bologna (Emilia-Romagna, Northern Italy), and R. schowii, described by Vincenzo Tineo from Vittoria and Terranova (Sicily), usually regarded as synonyms of R. gracilis , are here lectotypified and their taxonomic status discussed. Thanks to our study, the presence of R. gracilis in Italy is confirmed and, now, it is reported in a national conservation framework.
