Brown eyed susan, or....?

These flowers have just started to bloom in my front lawn.
When I saw these opening up, my initial thought was that they must be brown-eyed susans, but the xeriscape association database that I've been going to first for help in ID of local plants has photographs showing brown-eyed susans as slightly different looking. So now, I'm not sure.
If anyone can give me their thoughts, that would be great!

It does look like a rudbeckia to me - the classic brown-centered yellow daisy, the fuzzy (prickly-looking, almost) leaves.

This morning they show more shading towards the center of the petals, which leads me to conclude that I have the Gloriosa Daisy variety of Rudbeckia. It seems to have been developed in the 1950's by the Burpee Company. I would have been happier with the "original" but these are pretty and not getting any care, so I'll leave them where they are for now, and perhaps try to collect their seed and spread them a bit next year.
Thanks for your help.
