This AM while trying to identify today's offering of a Arizona desert bloomer, I found this page, and have to say, this sure looks a lot like my ?mesquite?
So, maybe my sweet little yellow puff of a flower belongs to the commonly named, whitethorn acacia.
Yep, still learning, still making bad identifications. Sorry, some of these are really tough for an undereducated layman guesser! LOL
* And, no, I have not found the identity of the desert bloomer - - yet.
