truncate saltbrush, wedge orach, wedge orache, wedgeleaf orache, wedgescale, wedgescale orache, wedgescale saltbush

Habit Herbs or subshrubs, perennial, decumbent-prostrate, unarmed, mainly 0.5–8 dm and spreading to 15+ dm wide, unarmed, white scurfy when young; branches not angled. Herbs, typically erect.
Stems

simple or more commonly branched throughout, mainly 2–8(–10) dm, branches mostly obtusely angled;

herbage scurfy, becoming glabrate.

Leaves

many, alternate, subsessile or short petiolate;

blade 1-veined, spatulate or obovate to oblong or elliptic, mainly 5–30(–40) × 2–9(–12) mm, base attenuate, margin remotely dentate to subentire, apex obtuse.

alternate or proximalmost opposite, short petiolate proximally, sessile and often cordate-clasping distally;

blade ovate to deltoid or oval, 4–30(–40) × 3–30 mm, base truncate or subhastate to rounded, margin entire or dentate, apex acute to obtuse.

Flowers

in axillary glomerules.

Staminate flowers

in small, terminal, leaf-bracteate glomerules 1.5 mm wide.

in glomerules mainly in distal axils;

sepals 3–5.

Pistillate flowers

solitary or in few-flowered clusters in almost all but distalmost leaves.

Seeds

dimorphic: black, 1.5–1.7 mm, or brown, 2 mm.

brown, 1–2 mm wide.

Fruiting

bracteoles red-fleshy at maturity, sessile or short stipitate, strongly veined, rhombic, convex, 3–6.6 × 2.8–4.5 mm, united at base, margin toothed, apex obtuse to acute.

bracteoles scarcely compressed, 2–3 mm and as wide, apex truncate to broadly rounded, with 3 (or more) teeth across summit, surfaces smooth (or rarely tuberculate).

Discussion

The red-fleshy fruiting bracteoles are diagnostic of this introduced perennial, which is multi-stemmed from an often buried woody caudex.

The Australian species Atriplex muelleri Bentham is somewhat similar. It has been has reported, but not verified, in the North American flora.
