Discussion

Atriplex gmelinii var. gmelinii occurs with Elymus, Juncus, Salicornia, Distichlis, Arenaria, Glaux, and Mertensia. Plants included herein vary considerably both in stature from diminutive plants a few centimeters to very large ones to more than 7 dm, and they also vary in size and shape of leaves from linear to lanceolate or ovate. Dwarf plants with obovate or broadly oblong leaves form the basis of Atriplex drymarioides, which has been considered to be of conservation concern. Plants of similar stature but with narrower leaves occur commonly below the high-level oceanic tides, while plants with broad, thin and occasionally hastate leaves are present in immediately adjacent areas above the level of the tide.
