Résumé :	Giemsa C-banding is utilized for the first time to characterize eight taxa of the genus Serapias. Heterochromatin distribution indicated that the Serapias species form a very homogeneous group. All the species possess chromosome pairs with similar heterochromatin patterns. C-banding showed conspicuous bands located around the centromeres, with some het-erochromatic short arms. There was more heterochromatin in S. apulica and S. nurrica than in the other taxa. Extensive centromeric heterochromatin may indicate recent structural rearrangements in the chromosome complement. Taken altogether, karyomorphology indicates a rather recent origin for the genus Serapias, which might also account for the small amount of interspecific variation observed.
