Flowers unisexual, monecious, in dense bracteate heads or spikes. 
Male flowers with a perianth of 3-6 scales, or without a perianth, but 
irregularly intermingled with slender narrowly clavate filaments, or 
spathulate or cuneate scales, which are often variously toothed or lobed. 
Stamens with free or connate filaments and basifixed, linear, oblong or 
cuneate, 2-celled anthers, opening by longitudinal slits; connective 
sometimes produced beyond the apex of the cells; no rudiment of an 
ovary. Female flowers with a perianth of scales or fine hairs, some- 
times accompanied by slender spathulate or clavate bracteoles. Ovary 
Superior, 1-celled, sessile or stalked ; style simple, terminal, persistent ; 
stigma unilateral, elongate ; ovule solitary, pendulous from the apex of 
the cell, anatropous. Fruit sessile or stalked ; pericarp thin and mem- 
branous, or thick with a spongy outer layer, and a hard, woody inner 
layer. Seed albuminous, testa thin; embryo cylindric, axile.-—Peren- 
nial aquatic or marsh herbs with creeping rhizomes. Leaves alternate, 
linear or strap-shaped, sheathing at the base; veins parallel. Flowers 
small or minute, sessile, bracteolate or ebracteolate, densely crowded 
into globose heads or cylindric spikes along simple or branched axes, 
with or without leafy bracts at their base. The male inflorescence 
terminal. 
A small order of two genera and about 25 species, very widely dispersed.
