I just looked at the Florida ISB Atlas of Vascular Plants and Phyllanthus tenellus is found in my county and the pictures look just like it. Normally, this and the other Phyllanthus are "pull on sight" weeds for me, too. I'm conducting an experiment to see what the caterpillars using it turn into. I'm 99% sure they're moths, but that doesn't mean I love them any less.
