Entomology (Study of Bugs)/Spider ID


Unknown Spider
Unknown Spider  
I live in Southwest Utah, St George/Washington City to be more precise, and found this spider in one of my recently flowering plants. In my attempt to identify it I believe it to be a variety of "desert shrub spider" but I can't find anything more specific than that. Can you help, please?


Thank you for including the image, which shows the underside of a Banded Garden Spider, Argiope trifasciata .  Here is more about them:


Desertshrub spiders spin a vastly different kind of web, and they do not get as large as this spider:


Thanks for making an attempt to do your "homework" ahead of time, I truly appreciate that effort.

I answer insect and spider identification questions ONLY. Attach images if possible. No "what bit me?", "what do I feed this bug in captivity?", or science fair project questions please. NO TECHNICAL QUESTIONS ABOUT INSECT PHYSIOLOGY.
