Polygonella ciliata, the fringed jointweed or hairy jointweed, is a plant species endemic to Florida. It is found in pinelands and sandy pine barrens at elevations less than 50 m, in central and southern parts of the state. Polygonella basiramia is treated as a variety of P. ciliata by some authors, but classed as a separate species by Flora of North America and other recent publications. It is very similar but branches mostly at or below ground level.
