Parish's brittlescale, Parish's saltbush, Parrish's brittlescale

bracteate orach, bractscale, saltscale, stinking orach

Habit Herbs, erect or spreading to prostrate, 0.5–3 dm; branches almost horizontal to ascending, fragile, white scurfy or villous (in var. parishii). Herbs, annual, erect or sprawling, usually branched often forming tangled mats to 10 × (3–)5–20 dm, ascending branches sparsely scurfy.
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).

many, subsessile or very short petiolate;

blade subconcolorous, lanceolate to oblong, elliptic, or oval, (8–)10–30(–40) × 3–12(–15) mm, margin sharply dentate to entire.

Staminate flowers

mostly in distal axils pistillate in proximal axils, or mostly in terminal spike (var. persistens), or partly so (var. subtilis).

in glomerules in terminal spikes or panicles 3–20 cm, or reduced to solitary, rounded, terminal glomerule.

Pistillate flower

in small clusters, axillary.

Seeds

dark brown or almost black, 0.8–1.5 mm.

brown, 1–1.3(–1.5) mm.

Fruiting

bracteoles sessile, ovate or rhombic, slightly compressed to thickened, 2–3.5(–4) mm and about as broad or sometimes broader, often subhastately lobed, united 1/2 of length, entire or with few teeth on each side, tuberculate on 1 or both faces.

bracteoles sessile or subsessile (stipe to 1 mm), cuneate-orbicular to obovate, somewhat compressed, 2.1–3.5 × (1.7–)2–3.7 mm, united 1/2 of length, margin sharply and often slenderly toothed beyond middle, faces often rather strongly veined, smooth or with 1 or more slender or flattened appendages.

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.
