"Arenaria paludicola" is a species of flowering plant in the pink family known by the common names marsh sandwort and swamp sandwort. It is native to the coast of western North America, where it is known from only a few remaining occurrences. It is a federally listed endangered species in the United States. It is present in two native locations in San Luis Obispo County, California, and it has been reintroduced nearby in Nipomo and Los Osos. [http://cnps.web.aplus.net/cgi-bin/inv/inventory.cgi/Go?_id=arenaria_paludicola&sort=DEFAULT&search=Arenaria%20paludicola CNPS Inventory] ] It is known from historical occurrences in Washington, [http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=250060022 Flora of North America] ] but it may have been extirpated from that state. [ [http://plants.usda.gov/java/profile?symbol=ARPA7 USDA Plants Profile] ] The plant may still exist in northern Mexico, but these occurrences are unconfirmed. The plant grows in wet areas, such as marsh and bog. This is a perennial herb which grows erect or trailing and draping over nearby plants and other objects for support. The slender stems are hairless and shiny, sometimes grooved, and approach 90 centimeters in maximum length. The stem has nodes at intervals and the nodes may root. Leaves are very narrow and lance-shaped. The inflorescence is composed of a single white flower. The fruit is a toothed capsule containing up to 20 tiny brown kidney-shaped seeds. Threats to the survival of this species include the destruction and alteration of its wetland habitat, shrinking of the local water table, and human activities such as off-roading.
