Found under a rock
perianth 2.5-3 mm long, glabrous; involucre about 2 mm long, peduncle 2-2.5 mm long
It kept running away from me, so unfortunately this is the best side shot that I got.
Some kind of rattlesnake?
They are in full bloom right now
It appears to have 4 sepals, 4 petals, and 6 stamens
I have other pictures of this guy if you need to see more characteristics.
