Comments on the earliest validly published varietal name for the Corsican pine

The correct varietal name for the Corsican pine, occurring in Corsica, Sicily and Calabria, is P. nigra var. corsicana (Loudon) Hyl., based on P. laricio var. corsicana Loudon. The Corsican pine is often referred to as P. nigra var. maritima (Aiton) Melville, based on P. sylvestris var. maritima Aiton, but the type of the latter is conspecific with P. halepensis. The Corsican pine belongs to P. nigra subsp. salzmannii, the westernmost of the two subspecies of the variable P. nigra.
