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.
