Small or fairly large, succulent perennials, perhaps annual in some species; stems erect or decumbent-ascending. Leaves grass-like to fairly large and broad, sheathing at the base. Inflorescence terminal, usually lateral as well, simple or compound, the ultimate branches composed of individual scorpioid cymes sub-tended by inconspicuous bracts. Flowers small (in our species), regularly 3-merous. Fertile stamens 6, essentially similar, the anthers longitudinally dehiscent, with conspicuous sterile connectives. Ovary 3-celled. Fruit capsular; seeds dry.
