This Iris looks a lot like 'Grand Canyon Sunset', but, the beard color is different. The beard in your pic is yellow and 'Grand Canyon Sunset's beard is orange. But, it's the best that I can come up with.
I noticed that "Colette Thurillete" has a tangerine beard too like "Grand Canyon Sunset" in all the plant database pictures.
From Nancy's picture ,the beards don't look tangerine.
