Annual 1–6 dm, the culms erect or ascending, often repeatedly branched; lvs 1–4 mm wide; middle sheaths mostly shorter than their internodes; infl 5–25 cm, ovoid or pyramidal, diffusely branched with one or two branches at a node, or the lower branches rarely fascicled or whorled; pedicels appressed, rarely diverging as much as 20º; spikelets mostly 6–15-fld, 1.2–2.5 mm wide; first glume 0.5–1.1 mm, half to three-fourths as long as the lowest lemma; lemmas 1–2.2 mm, individually deciduous from the rachilla, on which the paleas persist; grain pyriform, slightly compressed, 0.5–1 mm; 2n=60. Moist ground, especially as a weed in gardens and waste places; widespread in our range, s. to C. Amer. and W.I. E. tephrosanthos Schult., a weed mainly of trop. S. Amer., occurs rarely and sporadically with us. It has spreading pedicels like E. frankii, but is otherwise more like E. pectinacea.
