Polygonum basiramia
Also called Hairy Wireweed, Florida Jointweed
Polygonum basiramia (synonym Polygonella basiramia) is a rare species of flowering plant in the knotweed family known by the common names wireweed, hairy wireweed, purple wireweed, and Florida jointweed. It is endemic to Florida in the United States, where it is limited to the central ridges of the peninsula, including the Lake Wales Ridge. It is threatened by the loss and degradation of its habitat. It is a federally listed endangered species of the United States.
This plant is a member of the Florida scrub plant community. It occurs in scrub dominated by Florida rosemary, sand pine, other pines, and oaks. The soil is almost entirely composed of sand and it holds little water or nutrients. The plant occurs in openings in the scrub which are maintained by periodic wildfires. Other plants in this habitat include Calamintha ashei, Cnidoscolus stimulosus, Eryngium cuneifolium, Euphorbia floridana, Hypericum cumulicola, Lechea cernua, Licania michauxii, Paronychia chartacea, Polanisia tenuifolia, Polygonum polygama, Selaginella arenicola, and Stipulicida setacea.
