Eriogonum codium
Also called Umtanum Desert Buckwheat, Umtanum Desert Wild Buckwheat
Eriogonum codium is a species of wild buckwheat known by the common names basalt desert buckwheat and Umtanum Desert wild buckwheat. It is endemic to Washington in the United States, where it is known only from Hanford Reach National Monument in Benton County. It was discovered in 1995 during an inventory of the biodiversity of the monument and described to science in 1997.
There is only one known population of this plant. As of 2005 it contained 4418 individuals. The population occurs on a rocky ridge 2.5 kilometers long by 30 meters wide. The ridge is composed of a basalt lava flow which is part of the Wanapum Basalt, a geological formation. The plants grow on substrates of basalt with a pumice soil covering. The substrates are exposed and experience harsh conditions with high winds. The habitat is shrubsteppe. Associated plants include Grayia spinosa, Salvia dorrii, Phacelia linearis, Cryptantha pterocarya, Camissonia minor, and Bromus tectorum. Western harvester ants (Pogonomyrmex occidentalis) collect, transport, and apparently consume the seeds of the plant.
