= Phagnalon × intermedium (Lag.) Pau (1931: 51) View in CoL [ Ph. rupestre View in CoL (L.) DC. × Ph. saxatile View in CoL (L.) Cass.]

Notes:—The locality and collector number indicated in the original description refer to northeastern Spain: “Hab. - Barcelone, massif du Tibidabo vers Belesguart [Belesguard]” and “4432”. Sennen indicated that this was a hybrid between Phagnalon saxatile View in CoL × Ph. rupestre View in CoL [sub Ph. tenorii ]. We selected as the lectotype the specimen BC-SENNEN 945731 that matches quite well the original description, is kept in Sennen’s personal collection and is in a good state of preservation. We studied the original gathering deposited at BC and verified that the specimens show intermediate characters attributed to hybridization between Ph. rupestre View in CoL and Ph. saxatile View in CoL : the outermost and middle involucral bracts wider and obtuse, similar to those of Ph. rupestre View in CoL , but frequently with undulate margins, like those of Ph. saxatile View in CoL (see taxonomic notes under C. × intermedia View in CoL ). However, we observed that the outermost and intermediate bracts were acute in some capitula.
