Art, nice photos and comparative. I agree with you.
I have grown Sal's Corleone next to my Aldo's Palermo Red and they are the same. I have several starts of the Acciano fig and the leaves are similar if not the same as Sal's Corleone and Aldo's. I have yet to see Mario post detailed photos of the Acciano fig which I think is the same as the ones mentioned. It would be nice to see pics of the leaves and the fig close up. I'm suspecting that Acciano is another name for this popular variety which has many synonyms.
Bob, you are right about how figs behave in different climates. One example is the Nordland fig. I have Nordland growing next to me Longue d'Aout. There are subtle differences but I believe the two are one in the same variety. I suspect the Nordland fig adapted to a climate zone, becoming a sport of the LdA. It got passed around as a totally different variety under a different name but in reality, it is probably genetically the same as LdA. I believe that's how we got Sal's Corleone, Aldo's Palermo Red, Acciano, Sicilian Red, Pan y Vino Dark, and so many others.
