Text appearing in blue on this page will not appear in the printed book; it will be displayed only on the Web. Specimen numbers are hyperlinked to records in the Consortium of California Herbaria data view where possible. Taxa are hyperlinked to entries in the Jepson Interchange via the "[Online Interchange]" link.
Annual or subshrub, glabrous.
Stem: generally many-branched, appearing jointed when young; internodes green to glaucous, fleshy when young.
Leaf: opposite, sessile, decurrent; leaf pairs fused at base, enclosing stem.
Inflorescence: spike, terminal, cylindric, dense; bracts leaf-like; flowers generally 3 per axil, sessile, sunken in fleshy bracts of distal internode, adherent to each other and to bracts, forming a 3-parted cavity at flower-fall.
Flower: calyx fleshy, 3–4-lobed at tip, ± deciduous in fruit; stamens 1–2; stigmas 2–3.
Fruit: wall membranous, free from seed.
Seed: vertical; seed coat membranous, pale brown, hairy [ papillate].
± 50 species: ± worldwide. (Greek: salt horn) [Kadereit at al. 2007 Taxon 56:1143–1170] Needs study. Salicornia subterminalis moved to Arthrocnemum.
1. Subshrub, some stems vegetative only; central flowers of a node separating lateral flowers, flowers in a horizontal row
2. Woody stems spreading to erect; longest spikes with 12–40 fertile nodes ..... S. pacifica
2' Woody stems creeping; longest spikes with 7–14 fertile nodes ..... S. perennis
1' Annual, all stems terminated by inflorescence; lateral flowers of a node generally meeting below central flower, flowers in a triangle.
3. Lf, bract tips generally acute, sharp-mucronate; inflorescence internode length < width ..... S. bigelovii
3' Lf, bract tips obtuse to ± acute, not sharp; inflorescence internode length >= width
4. Infl internodes ± cylindric; central flower ± > lateral flowers; anthers 0.3–0.5+ mm, exserted before dehiscence ..... S. depressa
4' Infl internodes widest distally; central flower >> lateral flowers; anthers 0.2–0.4 mm, generally dehiscing inside flower, generally not exserted ..... S. rubra
