Perennial; culms erect, often wiry, finally branching, sometimes 
becoming decumbent or even prostrate and woody at base, with 
upright branches, mostly not more than 1 m tall; sheaths often over- 
lapping below; blades flat or folded, rather firm and stiffly spread- 
ing, usually pubescent, commonly 15 to 25 cm long and 6 to 10 mm 
wide; panicles mostly narrow, from loosely spikelike to rather open, 
attenuate at summit, usually 10 to 20 cm long, the branches short and 
crowded or ascending and 1 to 2 cm long, approximate or, especially 
the lower, 1 to 3 cm distant, these rarely to 5 cm long and spreading 
or reflexed: spikelets about 2mm long, the bristles 5 to 10 mm long, 
sometimes scarcely exceeding the spikelets; fertile lemma acutish, 
finely but strongly cross-ridged (fig. 318). 
This species is exceedingly variable. On dry slopes the culms 
are sometimes rigid, decumbent, and rooting at the nodes with 
erect flowering branches. The panicles i in such plants may be sub- 
spikelike or open with spreading distant branches, 1 to4 cm long. In 
Chase 6519 both forms of panicle were borne on the same individual. 
Open-panicled plants were described as Panicum brachiatum, P. 
paractaenoides, and P. dumetorum. Numerous intermediate speci- 
mens connect this form with typical Setaria setosa (fig. 319).
