Annual, much branched throughout, the branches slender or stout, 0.7-2 dm. long, pros- 
trate or spreading, terete, furfuraceous, often reddish; leaves numerous, imbricate, alternate, 
sessile, the blades ovate or broadly ovate, 4-10 mm. long, acute, rounded or subcordate at the 
base, entire, thick, densely furfuraceous; flowers monoecious, solitary or few in the axils; calyx 
4-parted; fruiting bracts sessile, rounded-deltoid, 2-3 mm. long and as broad or broader, com- 
pressed, somewhat hastately lobed at the base and denticulate or crenulate, acute or acuminate 
at the apex, the sides smooth; seed 1 mm. long, brown, the radicle lateral.
