Yeah I see this almost every year in my garden. It happens to any type of iris. It seems to be triggered by extreme temperature changes during bud formation. I've seen it on bearded, beardless, and crested. I probably see it most often on bearded, because they make up the bigger chunk of my collection. And when I say "it" -- I mean irises with "other-than-the-normal-3-parts. Sometimes it's 4-parts. Sometimes it's 5-parts. Sometimes it's 2-parts. Once I even had it with 1-part.
