Another problem flower

Here is another flower growing in Tucson Arizona at about 750 m in elevation. Dry location above Santa Cruz River.

Small flower (a few mm). Herbage with stellate hairs, somewhat succulent, apetalus, 5 stamens, yellow sepals

 

I figured it out. Tidestromia lanuginosa.

 

Lovely little plant, well suited for its environment. Thanks for posting it.
