Karyological study of some plant taxa from Greece

Liveri, E., Phitos, D. & Kamari, G. 2021: Karyosystematic study of some plant taxa from Greece. [In Kamari, G., Blanché, C. & Siljak-Yakovlev, S. (eds), Mediterranean plant karyological data 31]. – Fl. Medit. 31:346-354. http://dx.doi.org/10.7320/FlMedit31.346 Chromosome numbers and karyotype morphology are given for four taxa of the Greek flora together with distributional and taxonomic notes. The chromosome number (2n = 16) and karyotype morphology of Allium sphaerocephalon subsp. arvense is reported for the first time in material from Kithnos island (Kiklades). The studied population of Cyclamen graecum subsp. graecum shows the chromosome number 2n = 84, which is in accordance with previous reports from Greek material of unknown origin. A new subpopulation of Cynara cyrenaica from E Crete is presented and karyologically investigated confirming the previous chromosome number (2n = 34), whereas microphotograph of the karyotype is provided here for the first time. Furthermore, chromosome data for Ornithogalum fimbriatum subsp. fimbriatum reveal a diploid karyotype (2n = 12), which constitute the first karyological contribution from a Greek population belonging to the typical subspecies.
