Taxonomic note on some ltalian Bearded Irises: Iris relicta Colas. nom. nov. and Iris bicapitata Colas. sp. nov.
The difficulties in the subdivision of infrageneric taxa in Iris L. have created great taxonomic problems even at the level of nomenclatural and taxonomic synonymies. The eases of I. suaveolens (N. Terrace.) N. Terrac. ex A. Terracc. and I. biflora L. sensu Petagna are here analysed. Then, I. relicta Colas. nom. nov. and I. bicapitata sp. nov. are proposed.
