Unfortunately I bought so many iris last year from so many vendors...and I didn't think to number the NoIDs and record which ones came from where...so I cant' trace the source.
Tom, as I was poking around a few websites last night I looked at Copatonic and Rustler...but the beard on Copatonic is too yellow, my NoID's beard is a russet color. The flower color is probably close (maybe a little light) because the Copatonic photo was taken in full sun which washed it out a bit....and I can't remember why but I decided Rustler wasn't quite the same either although it was very close! I checked a couple of the Rustler 'children' and they were also close...but none we quite right. As I've mentioned before, I love a puzzle so whenever I find a seller who carries the older varieties I enjoy scanning through...that's how I noticed Rogue and Leslie Dawn.
Anyway thanks everyone for the helpful suggestions...keep them coming, and if I figure it out I will share it with all of you! For the time being I have dubbed it 'Mystery Brown' , not too creative but better than 'that brown NoID' don't you think?
...and Debra that brown iris you have is another pretty one (I like the browns too)! I'll keep my eye out as I'm searching to identify my Mystery Brown NoId...if I see any likely contenders I'll send them your way.
