Atriplex coronata

Atriplex lindleyi

crownscale, wedgescale

Lindley's saltbush
Habit Herbs, erect or decumbent, 0.5–6 dm; branches terete, fructiferous almost to base, scurfy when young. Herbs, erect or suffrutescent perennial, 1.5–4 dm, woody at base.
Stems

terete, finely white-mealy when young.
Leaves

alternate, subsessile or proximal short petiolate;

blade ascending, oblong, oblong-ovate, or lanceolate to elliptic, 5–40 × 2–10 mm, thin, base acute to obtuse, margin entire, apex acute to acuminate.

alternate, petiolate proximally, becoming sessile distally, crowded;

blade oblanceolate or proximal rhombic, 10–20(–30) × 3–15 mm, base cuneate or attenuate, margin entire to repand-denticulate, apex acute to obtuse, scurfy.
Flowers

of both sexes in small axillary glomerules, 5-merous.

Staminate flowers

in axillary glomerules, in short axillary spikes or terminal spikes.
Pistillate flowers

axillary, solitary or few and clustered below staminate.
Seeds

light brown to amber, 1–1.5 mm.

dimorphic: dark reddish brown, 1.5 mm wide, or black, slightly smaller;

radicle basal, horizontal.
Fruiting

bracteoles almost sessile, broadly cuneate, 2–5 × (2–)2.5–5 mm, united to summit, truncate at summit, sides smooth or obscurely tuberculate.

bracteoles sessile, bordered by narrow horizontal wing or acutely angled, broadly turbinate or hemispheric, united except at minute apical tips, 6–12 mm, spongy and inflated at maturity, flattened at summit.

Discussion

Varieties 3 (3 in the flora).

Although placed within the Atriplex argentea species complex by P. C. Standley (1916), this taxon appears more nearly allied to A. cordulata, differing mainly in leaf shape, round-ovate or deltoid-ovate to elliptic or lanceolate (not ovate to cordate-ovate), and markedly tuberculate faces of the fruiting bracteoles.
