| Abstract: | Based on general morphology, spore measurements and ornamentation (scanning electron microscope), genome size estimation, and molecular systematics (trnL-trnF IGS), we show the extreme systematic complexity within the European representatives of the genus Ophioglossum. In particular, three hybrids from Tuscany are described: the tetraploid O. × pierinii Peruzzi, Magrini, Marchetti & Viane, seen as the hybrid between diploid O. lusitanicum L. and hexaploid O. azoricum C.Presl; the tetraploid O. × giovanninii Peruzzi, Pierini, Magrini, Marchetti & Viane, seen as the homoploid hybrid between tetraploid O. vulgatum L. and tetraploid O. × pierinii Peruzzi, Magrini, Marchetti & Viane; the pentaploid O. × pseudoazoricum Peruzzi, Pierini, Magrini, Marchetti & Viane, seen as the hybrid between hexaploid O. azoricum C.Presl and tetraploid O. vulgatum L. All the three new taxa grow in different localities in the Monte Pisano mountain range. |
