Ya, its sometimes hard to be sure when they don't come to you labeled (or come to you miss-labeled)... I usually go to the Iris Wiki for confirmation but looks like they only have one pic of it too so would be nice to have more:

You could try posting a photo of yours in the iris forums and asking others what they think...not sure anyone could help but its worth a try.
