Stems few or solitary, from a woody root, usually erect, sometimes decumbent, 3-12 dm. 
high, stout or slender, simple or sparsely branched below the inflorescence, sometimes with 
weak sterile branches at the base, green, or glaucescent below, glabrous below or bifariously 
puberulent, very rarely pilose with soft viscid fulvous hairs, pilose or short-pilose above but 
the pubescence usually bifarious below the inflorescence, the internodes usually elongate;
