Chenopodiaceae - Salicornioideae - Salicornieae - Halosarcia Paul G.Wilson

Description:

  • Perennial dwarf shrubs, usually thinly woody, low, glabrous, apparently built up of many, superposed, ± tubular segments which are green or glaucous and ultimately shrivel and fall away from stem
  • Leaves opposite, forming an insignificant fleshy bilobed rim at apex of each internode; sclereids 0 in chlorenchyma
  • Inflorescence a spike-like cyme (thyrse), usually terminal to branchlets, consisting of 3-flowered cymules each in axil of opposite, usually connate succulent bracts
  • Flowers usually bisexual or rarely pistillate, sessile
  • Perianth 3-lobed at apex, funnel-shaped
  • Stamens 0-1, abaxial; filament initially turgid and terete, eventually lorate, sometimes indurated towards base
  • Ovary vertical, membranous or succulent, ovoid; ovule suspended from a basal funicle; style short, with 2 or 3 stigmas
  • Seed erect, ovoid to circular, smooth, coat membranous to crustaceous; perisperm present, lateral; embryo curved
  • x = 9
