Linnaeus, 1753 (Liliaceae) is a genus of geophytes, represented in Greece by 29 taxa. Most of the Greek species are endemic to the country and/or threatened. Although their classical cytotaxonomic studies have already been presented, no karyomorphometric analysis has ever been given. In the present study, the cytological results of Fritillaria montana
Hoppe ex W.D.J. Koch, 1832 group, which includes F. epirotica
Turrill ex Rix, 1975 and F. montana
are statistically evaluated for the first time. Further indices about interchromosomal and intrachromosomal asymmetry are given. A new population of F. epirotica
is also investigated, while for F. montana
, a diploid individual was found in a known as triploid population. Paired t-tests and PCoA analysis have been applied to compare the two species.
