ID on Minature Dwarf

Can anyone tell me what this miniature dwarf is called? It is 3-4 inches tall and is a very prolific spreader. It blooms very early compared to my other iris and even early compared to my dwarf iris, candy apple.

I have one similar, but I'm afraid it's a noid, too. I am beginning to think it may be a I. pumila, and have a couple different "clones" of I. pumila coming to use as "test plants". It's usually the first to bloom, and goes at it for a long time, too! ...Arlyn

It certainly looks the form of a pumila, Arlyn. The original request for ID looks like a cultivated miniature dwarf. Where did you obtain it, or was at the house when you bought it.
