Discussion

Arida carnosa is recognized by its subshrubby habit, glabrous, glaucous, and succulent stems, reduced scalelike leaves, and absence of ray florets. It occurs in or around alkaline salt flats, where it is associated with other salt-tolerant genera such as Sarcobatus, Distichlis, and Atriplex.
