graceful sandmat, Euphorbia hypericifolia

Sandmats are interesting little plants, often growing in sand or disturbed soil, and sprawling along the ground. They are worth a close look, but don't touch. They're poison, and can even cause dermatitis in a few people. And if you do touch them, and later thoughtlessly rub your eyes, be careful as you drive to the ER. But they're still worth a close look. There are no petals here. The white bits are modified leaves. But there are an amazing number of flowers. I'm guessing about 50 active, with many more still developing. Each stamen and pistil is a separate flower. Seems strange, but it works. Euphorbia is one of the largest genera of plants, distributed worldwide. Graceful sandmat grows in AL, AZ, CA, FL, GA, and HI. Putnam Co FL, 1/28/13. Spurge family, Euphorbiaceae.
