We've seen suncups in several places in 2016 and 2017.  We've learned to spot the pistil ball.  Love the yellow color and the red accents.  My best guess is Camissonia kernensis.  However, when the eFlora entry says &quot;Cross-pollinated. Related to Camissonia parvula, Camissonia pubens, Camissonia pusilla. Subspecies intergrade extensively. &quot;, I think it's time for me to stop.
