| Résumé : |
"Hymenonema is a Greek endemic genus consisting of two species, H. laconicum and H. graecum, occurring in the lowlands of S Peloponnisos and on most of the C Aegean islands, respectively. Morphological investigation of 20 gatherings covering the entire distribution range revealed clear morphological differences between the two species, mainly in pappus, achenes, anther tube, ligules and basal leaf characters. A corresponding emended identification key to the species is given. Karyological investigation of 11 accessions included karyotypes, idiograms and karyological indices for both species. Six karyomorphological parameters were also statistically analysed. Populations with intermediate morphological characters between the two species are recorded for the first time and their relationship with the typical two species is discussed. The geographical distribution of the genus is mapped and doubtful locations are commented on. The cytotaxonomic data and the geographical distribution of the species support the characterization of H. laconicum and H. graecum as schizoendemics. The conservation status of both species is suggested as Vulnerable (VU) according to IUCN criteria." (source : auteurs) |
