Resumen de A New Species of Rhaponticoides (Asteraceae) from Southern Italy

Domenico Puntillo, Lorenzo Peruzzi

• A new diploid (2n?=?30) species, Rhaponticoides calabrica, is described from Calabria and Basilicata (southern Italy). This species differs from the closely related R. centaurium � an endemic of Apulia and northern Basilicata � by different flower colour (white in the former, purplish in the latter), width of membranous margin of phyllaries (1.8?±?0.4 mm vs 0.8?±?0.3 mm) and pappus length (6.8?±?0.9 mm vs 9.1?±?1.0 mm). The two species are completely allopatric and seem to have also different chromosome numbers.
