Sparsely furfuraceous, succulent, annual herbs. Leaves alternate, petiolate, the blades 
broad, repand-dentate. Flowers small, monoecious, in axillary glomerules; staminate flowers 
without bracts or bractlets, the calyx subglobose, membranaceous, 3- or 4-parted, 2 of the seg- 
ments larger than the others, spatulate, not appendaged; stamens 3 or 4, the filaments short, 
broad, flattened; pistillate flowers bibracteate, the bracts conduplicate, obcompressed, cari- 
nate, connate below the middle, in fruit narrowly winged dorsally, the wings crenulate; 
stigmas 2, short, filiform. Utricle enclosed by the bracts, compressed, the pericarp thinly 
membranaceous, free. Seed compressed, orbicular; embryo hippocrepiform or subannular, 
surrounding the copious endosperm; radicle superior.
