One spurge of many

I'm pretty sure this is some variety of spurge (Euphorbia) - maybe Seaside Spurge? - since it grows everywhere in the dunes at the beach? Puzzling through the thousands of spurges just tries my patience way too much.

;-)

The early flies seem to appreciate it, whatever its name is. I do, too, for the bit of color before there's anything else to draw my eye. (Even if it is yellow!)
