I'm still pretty sure it's one of the pallida clones.....which means it's a *species* iris......iris pallida. Being a "species", when that plant sets seed the seedlings will be *almost* identical to the parent plant, ....I said *almost*. There *can* and often "are' very slight differences, and, "back in the day"....when someone noticed a single plant growing in a huge stand of them, that was just, that, little bit taller(or shorter , or more violet than blue, or 'whatever), he dug it up ...in other words, he "selected" that plant (and he also "collected" that plant). He took it home, planted it, and, as it grew, he divided it, and, when he did....all those divisions are *clones*....identical to the one he collected. The Dalmatica you mentioned is one such "form" of i' pallida....."Princess Beatrice" is another, as is "Odoratissima"....there are actually quite a few that have been "selected", "collected", and then "named", so, using Odoratissima as an example , it's 'full name" would be , " iris pallida, variety "Odoratissima" (selected and collected By) Jacquin in 1797....so, you can call it "pallida", or, you can call it 'Odoratissima"....both are 'correct'. If we were talking about PEOPLE, and describing me, for example, we would say Homo Sapiens (that's the species), the "bald one" (that would be the feature that was "different, caught someones eye, and caused me to be 'collected", or selected), they would say, " I'm calling this one , "Arlyn"....so my full moniker would be , "homo sapiens, var. "Arlyn".
Your noid MAY have been collected, selected, and "named"....or, it may have been a seedling, of a seedling, of a seedling that WAS collected and named, but, more likely , it's 'just" a clone of an un named iris pallida clone that has been passed along, gardener to gardener.
Cultivars like "Dogrose" , for example, came about because of , usually the "intermingling " of species.....hybridization, either natural (a bee) , or intentional (human ). It will be a long search to determine if your noid is "named", or not, and while the search can be a lot of fun, it can also be both time consuming and expensive (finding , buying, and growing "test plants" for comparison ). If it was me, I'd start on the AIS page that was linked, above, concentrating on the "named" I. pallida, ...not the 'cultivars " with I, pallida in their background...and comparing YOUR plant to the written descriptions of 'I. pallida".....you may 'hit the jackpot", or, you may not...it's possible you may need to go down a different path, entirely (if you find contradictory information about the 'descriptions" matching), either way, have fun
