deeply lobed, the lobes green, white-margined, acutely carinate, completely enclosing the 
fruit; pericarp adherent; seed horizontal, 1.3-1.5 mm. broad, neatly smooth, black and shining, 
the margin obtuse.

Ill-scented erect annual, 2-20 dm. high, much branched, the branches stout, ascending, 
often from a spreading base, obtusely angled, striate, glabrous or sparsely and coarsely farinose; 
petioles stout, half as long as the blades or shorter; leaf-blades rhombic-ovate, 2.5—-5 em. long,

yellowish-green, sparsely and coarsely farinose beneath, the upper blades smaller, ovate to 
lanceolate, acutely subhastate or serrate; flowers in large glomerules, these in very dense, 
stout, narrowly paniculate spikes, the branches of the inflorescence stout, erect or strongly 
ascending, sparsely leafy, the whole inflorescence yellowish; calyx densely and coarsely farinose;

Erect annual, 4-15 dm. high, usually ill-scented, much branched, often simple at the 
base, the branches ascending, often from a spreading base, slender or stout, obtusely angled,
