Map of select IRC data for peninsular Florida

IRC SOUTH FLORIDA Status: Imperiled

SOUTH FLORIDA Occurrence: Present

SOUTH FLORIDA Native Status: Native

SOUTH FLORIDA Cultivated Status: Not Cultivated

Comments: 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.
