Stem: young stems often ± pendent, slender, ± covered by leaves, hairy or glabrous. Leaf: small, awl- or scale-like, sessile, generally ± clasping stem, generally encrusted with excreted salt. Inflorescence: raceme or compound raceme on current or previous year's twigs; bract generally ± clasping. Flower: sepals 4–5, generally ± united at base, persistent; petals 4–5, free, deciduous to persistent, white, pink, red; stamens 4–5, free; nectary disk lobes 4–5, alternate or confluent with filaments; styles 3–4. Fruit: valves ± lanceolate. Seed: hairs in tuft at tip, > seed.
± 60 species: Eurasia, Africa. (Latin: Tamaris River, Spain) [Beauchamp et al. 2005 Plant & Soil 275:221–231] Invasive weeds with deep roots, especially along streams, irrigation canals.
