Habit | Herbs, erect or spreading to prostrate, 0.5–3 dm; branches almost horizontal to ascending, fragile, white scurfy or villous (in var. parishii). | Shrubs, dioecious, forming broad clumps, mostly (8–)1.2–20(–30) dm; branchlets striately and often sharply angled, glabrous or sparingly puberulent, often becoming bluntly spiny. | ||||||||||||||||||||
Leaves | numerous, all or nearly all opposite or almost all alternate, distal ones imbricate or widely separated, tending to recurve; blade lanceolate to ovate, (2–)4–10 × 3–8 mm, rigid, base mostly rounded to cordate, margin entire, gray to white, densely scurfy (or hairy). |
persistent, alternate; petiole 1–4 mm; blade grayish or greenish, ovate to deltate, rhombic, oval, or lanceolate, typically subhastate, (5–)12–32 × 4–16(–20) mm, base truncate to obtuse, margin entire (rarely toothed), apex obtuse and apiculate. |
||||||||||||||||||||
Staminate flowers | mostly in distal axils pistillate in proximal axils, or mostly in terminal spike (var. persistens), or partly so (var. subtilis). |
yellow, in clusters 1 mm wide, borne in panicles mainly 10–30 cm. |
||||||||||||||||||||
Pistillate flowers | in once-branched panicles. |

brown, 1–1.9 mm wide. |

Discussion | Varieties 5 (5 in the flora). The Atriplex parishii complex consists of a series of microphyllous, low clump-forming annuals apparently disjunct from each other in the Central Valley of California and in near coastal southern California. Often they occupy vernal pools that dry as the season progresses; the substrates in all cases evidently are saline or alkaline, or both. For the most part, the bracteate distal leaves are cordate to rounded at the base, and spreading to spreading-ascending, and the fruiting bracteoles are mainly less than 3.5 mm in length.
