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.

Key to Salicornia

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. Leaf, bract tips generally acute, sharp-mucronate; inflorescence internode length < width ..... S. bigelovii

3' Leaf, bract tips obtuse to ± acute, not sharp; inflorescence internode length >= width

4. Inflorescence internodes ± cylindric; central flower ± > lateral flowers; anthers 0.3–0.5+ mm, exserted before dehiscence ..... S. depressa

4' Inflorescence internodes widest distally; central flower >> lateral flowers; anthers 0.2–0.4 mm, generally dehiscing inside flower, generally not exserted ..... S. rubra
