The ploidy level of fificen populations of Scilla autumnalis L. was investigated in Sicily. On such basis, both tetraploid and exaploid levels were found occurring in the study area, in addi- tion 10 old and new other diploid populations. Furthermore, B-chromosome were found in the Favignana islet (Egadi archipelago, W-Sicily). The results are discussed here with respect to the occurrence of different ploidy levels in the whole distribution area of this species.
