Scop. Notes This species was observed and photographed on a sandstone outcrop approximately 1 km northeast of MDRS on September 20, 2015 (Fig. 25), however this plant was not collected due to time and equipment constraints. Common on sandy plateaus and Guterriezia - Bromus dominated scrub near MDRS, this species is a noxious weed found throughout the southwestern United States ( Welsh et al. 1993 ). This species was previously reported for the nearby San Rafael Swell ( Harris 1983 ) as Salsola iberica Sennen & Pau, which was later synonymized under Salsola tragus L. ( Mosyakin 2003 ). Further phylogenetic work has transferred this species to the genus Kali ( Akhani et al. 2007 ), now placed in the expanded Amaranthaceae ( APG III 2009 )
