4. SALICORNIA, Linn.

Annual or perennial leafless herbs, sometimes woody at the base. Stems cylindric, jointed, very succulent; branches opposite. Flowers minute, hermaphrodite or polygamous, sunk in cavities between the successive joints of the branches towards their tips, 3–7 together, free or connate at the base. Perianth obpyramidal, fleshy, flat at the top or rarely contracted; mouth 3–4-toothed. Stamens 1–2; anthers large, exserted, didymous. Ovary ovoid, narrowed above; styles 2, subulate, papillose. Utricle included in the spongy perianth, membranous, ovoid or oblong. Seed erect,, oblong or obovoid; testa thinly coriaceous or crustaceous, hispid with hooked hairs; albumen wanting; embryo folded, radicle inferior.

A small genus of about 8 species, found on most temperate or tropical seashores, and occasionally in saline places inland. The single New Zealand species also occurs in Australia and Tasmania.

Spikes terminating the branches and rather thicker than them, ½–2 in. long, the joints short, broader than long. Flowers frequently polygamous, 5–7 together on each
