Atriplex parishii
Atriplex wolfii
Parish's brittlescale, Parish's saltbush, Parrish's brittlescale
slender orach, Wolf's saltweed
simple or more commonly branched throughout, mainly 0.7–3.5 dm, branches terete;
herbage scurfy.
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).
blade concolorous, linear to narrowly lanceolate, mainly 4–25 × 1–3 mm.
very small, both sexes in the same sessile, axillary clusters.
mostly in distal axils pistillate in proximal axils, or mostly in terminal spike (var. persistens), or partly so (var. subtilis).
sepals 5.
dark brown or almost black, 0.8–1.5 mm.
brown, 1–2 mm.
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, ovate to cuneate in outline, 1.5–2.7 × 1.1–2.1 mm, apex truncate to attenuate, faces smooth or tuberculate.
Atriplex parishii
Atriplex wolfii
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.
