Phenology: Flowering mid summer–late fall.
Habitat: Alkaline soils, mostly on raised sandy hummocks in salt playas and mud flats

Ariz., Calif., Idaho, N.Mex., Nev., Oreg., Tex., Utah, Mexico.
Discussion
A dominant shrub of salt playas and mudflats in the American Southwest, iodine bush is easily distinguished from great distances by the dark hue of its stems. The blackish-colored shrubs stand in stark contrast to surrounding vegetation and on close examination can be easily distinguished from the opposite-branched, but vegetatively similar members of Sarcocornia.
Selected References
None.
Lower Taxa
