Although ranked by IRC as critically imperiled in Rare Plants of South Florida (Gann, Bradley and Woodmansee 2002), several new records have become available in several areas in South Florida. As a result, we re-ranked this as imperiled in 2014. It is apparently rare and scattered, but widespread. It is similar to other native Polygonum species, and perhaps easily overlooked.
