Staminate flowers | in subterminal, axillary glomerules. |
in glomerules on interrupted, leafy paniculate spikes. |
Pistillate flowers | in axillary glomerules. |
in small glomerules borne in leafy, paniculate spikes. |

Phenology | Flowering summer–fall. | Flowering spring–fall. |
Habitat | Disturbed places, with other ruderal weeds | Saline, fine-textured soils |
Elevation | 10-900 m (0-3000 ft) | 60-1500 m (200-4900 ft) |

Discussion | Atriplex parryi occurs with greasewood, saltbush, saltgrass, and Nitrophila. The cordate-clasping, sessile leaves and spiny branches distinguish this species from its nearest congeners. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
