Pilea microphylla (Linnaeus) Liebmann var. microphylla. Common name: Rockweed, Artilleryweed. Phenology: Jan-Dec. Habitat: Marl prairie, hammocks, pine rocklands, old rock and brick walls, urban areas, hammocks, especially in thin soil over limestone. Distribution: FL (perhaps more widespread as a native in the Southeastern US than just FL); West Indies; Mexico, Central America, and South America. Although listed by Radford, Ahles, & Bell (1968) for the Carolinas as "a weed in and around greenhouses, not established as part of our flora", this species is well-established and weedy in Charleston, SC and Savannah, GA. Native at least in FL, and perhaps further north, the original distribution unclear.
