Discussion

Atriplex hymenelytra occurs with saltbush, Larrea-Ambrosia, ephedra, and yucca. This is a handsome, rounded shrub with silvery white foliage, sometimes contrasting strongly with the peculiar substrates on which it grows. Its relationships to other of the southwestern species are recondite, but possibly it is allied to A. confertifolia, with which C. A. Hanson (1962) suggested an affinity.
