Iris sicula is not at all Gynandriris sysirichium !! This is a funny mistake appeared on Flora d'Italia by S. Pignatti (1982). Comparing them is like to put and elephant and an ant side by side !! Iris sicula is a bearded species, related to Iris mesopotamica, nothing in common with Iris pallida too. There are photo and text on Wiki ;-) Angelo Porcelli
