This study presents new chromosome numbers for two native Italian species: Crepis suffreniana (DC.) Steud. (Asteraceae), whose only Italian population is known for the Migliarino-San Rossore-Massaciuccoli Regional Park in Tuscany, and Dianthus furcatus Balb. subsp. furcatus (Caryophyllaceae), a taxon distributed in Italy in the western Alps. Concerning C. suffreniana , our count confirms previously published reports from France. For D. furcatus subsp. furcatus, we report a hexaploid level, contrasting with previous studies on D. furcatus s.l. from the Italian Alps, which documented only the diploid level.
