Staminate flowers in small, terminal, leaf-bracteate glomerules 1.5 mm wide. Pistillate flowers solitary or in few-flowered clusters in almost all but distalmost leaves. 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. Seeds dimorphic: black, 1.5–1.7 mm, or brown, 2 mm. 2n = 18.


Phenology: Flowering spring–early winter.
Habitat: Saline waste places, along roads and sidewalks, in marshes, in various plant communities

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.
