Discussion

Pavonia lasiopetala has become a popular cultivated plant in Texas, where it is also native. It is also used as a component in seed mixtures for ranges and pastures.

Pavonia spinifex has been reported from elsewhere in the flora area; such reports generally are based on misidentifications of other species. The species may be native in Florida, but the fruits easily attach to clothing and fur and the species has been introduced widely; its native range is not known. In Florida, it is found in seven counties north of Lake Okeechobee, from Duval to Brevard and Highlands counties. It appears to be most frequent on shell middens on the coast north of Cape Canaveral.
