Herbs , annual, 0.2-5.5 dm. Stems simple or freely branched, sometimes densely matted, prostrate, decumbent, ascending, or erect. Leaf blades narrowly to very broadly ovate, oblong, orbiculate, or reniform, 0.2-4.5 × 0.2-2.7 cm, base broadly cuneate, rounded, truncate, or nearly cordate, apex acuminate, acute, obtuse, or rounded; proximal pair of lateral veins arising at junction of blade and petiole. Flowers: involucral bracts 1-4.5 mm; tepals 2-2.8 mm, shorter or longer than bracts. Achenes light brown, symmetric, 0.9-1.2 × 0.6-0.7 mm, apex obtuse, mucro apical; stipe centered, short-cylindric, basally dilated.
Plant: annual herb; Prostrate, decumbent, ascending, or erect, simple or freely branched, sometimes densely matted, 3-55 cm tall
Leaves: narrowly to very broadly ovate, oblong or circular, 0.4-4.5 cm long, 0.4-2.7 cm wide, about as wide as long to longer than wide; apex attenuate, acute, obtuse or rounded; base broadly cuneate, rounded or truncate
INFLORESCENCE: inflorescences of few flowered axillary cymes, the lowermost flowers usually perfect, those above pistillate
Flowers: subtended by bracts ca. 1-4.5 mm long; tepals acute, loosely connivent at maturity; bracts shorter than or exceeding the tepals
Fruit: ACHENES symmetrical, 0.9-1.2 mm long, 0.6-0.7 mm broad, shining, hard and bony, ovoid, stipitate, enclosed by the perianth
Misc: Deserts, dry woodlands, roadsides, sand dunes, rock crevices, often in shaded and moist places
Notes: stems translucent; tepals subtended by 1-3 green bracts
