Description :

• Small to fairly robust herbs, sometimes with thalloid bodies only or developing stems on which leaves and inflorescences are borne
• Stems erect, branched, woody, often sparsely to densely covered with small, imbricate leaves or bracts
• Leaves dimorphous: (a) floating, linear, often branching dichotomously; (b) bract-like, hard, often dentate, in many species covering the abbreviated, fertile shoots
• Flowers single in axils of bract-like leaves, aggregated towards apices; spathella obovoid, apiculate, splitting laterally, apex remaining intact; flower recurved in spathella, becoming erect at anthesis, pedicelled
• Perianth 0 or of 2 minute, subulate segments situated on each side of stamen(s)
• Stamens 1 or 2, if 2, with filaments fused nearly to apex; pollen in monads or diads
• Ovary ovoid to fusiform; styles 2, subulate, papillate, usually recurved
• Capsule ovoid to ellipsoid, 10-ribbed, with all ribs running entire length of capsule, opening by 2 subequal valves; one or both persistent
