A new butterwort species (Pinguicula, Lentibulariaceae) from Northern Apennine (Italy)

Abstract

A morphometric and taxonomic study of Pinguicula in Northern Apennine was carried out. A new species belonging to sect. Pinguicula, previously referred erroneously to P. vulgaris L. and/or P. leptoceras Rchb., is here described as P. christinae sp. nov. The taxonomic relationship of P. christinae with other octoploid species, such as P. apuana Casper and Ansaldi, P. fiorii Tammaro and Pace, and P. vulgaris s.l. (including also its central Italian endemic subspecies) is discussed.
