Does anyone know what the difference is between ALCAZAR and Lent A. WILLIAMSON TB Iris? Looking at the database didn't help much. I have included a photo of what I thought was L.A. Williamson. Please advise.

Linda, when you looked them up in the database, did you scroll down a bit to view all the pictures for that cultivar? Sometimes that can give you a better overall view of the flower, as well as the leaves and the plant habit, branching on the flower stem, etc.

Looking at Alcazar, just my opinion but I think it has much more striping on the falls than the one in your picture. So my guess would be that it is Lent A.Williamson. The stripey area is shorter on it.

They are VERY similar though.

Elaine,
Thank you for your help.
That was my guess from the photos I was looking at also and the different sites I have looked at. I think the bearding is shorter on the L.A. Williamson also from Alcazar's which seems to run down their falls more.
Habit? I was given 6 apple boxes of these years ago and hurried to get them planted. With my heavy work load for years the poor things have been left on their own. I remember my Mother having these same ones (type that is) forever when I was a kid and I was always the kid that had to weed them. Oh the memories of it all~ the blisters, the dirty and broken nails, the cuts on my poor little hands and oh my knees and back.
Yep, I am a brute for punishment! I have spent the better part of two weeks now preparing to buy my Iris stock to start a county garden next year (2016). This should be fun! Right???!

It's really rare that one can ID an iris from a photo alone. There are several historics that look like yours. The best way to compare them is to get a known rhizome and plant it next to the unknown one and see if they grow to the same height, bloom at the same time, have the same fragrance, and then tear the bloom apart to compare them down to the last detail. I think you would get some good results by posting your question on the Iris forum. There are some really knowledgeable people there who grow and study the historic irises.
@crowrita1 has one of the largest collections of historics that I know of. Maybe he can weigh in on this question. Good luck!

tveguy3,
Excellent advise of doing a match. I do not believe the one I have is Alcazar, there are small differences but even small, they are differences.
Thank you for your help.
