Daylily flowers have a tendency to slight variations, the photo on the first site I linked to (the Russian one) looks spot on, and to my eye the others look as close as one might expect with variations but of course there are incorrectly named plants. Put them side by side to see the likeness.
Dave, sorry about that, I had done a lot of google image searching using colour as a guide, I found one on a 7 year old thread on GW
which was unknown but suggested it could be Autumn Red. The rest comes with what I find on google images, I don't deliberately go to any site but go to what google presents but I get your point.
