Seed generally erect
Species in genus: ± 250 species: temp to subtropical worldwide
Etymology: (Latin: ancient name)
Generally in alkaline or saline soils; some weedy; some accumulate selenium.
Annual < 2 dmSee the CNPS Inventory for information about endangerment and rarity.
Stems 1few from base, generally erect; branches ascending to erect, stiff, gray-scaly, becoming glabrous
