Publication: Ess. Agrostogr. 51, 171, 178. 1812.

Origin: Introduced from Europe

selected vouchers: WTU

Notes: FNA25: "Setaria verticillata is a European adventive that is now common throughout the cooler regions of the contiguous United States and in southern Canada. It is an aggressive weed in the vineyards of central California. Reports of S. carnei Hitchc. from North America are based on misidentification of this species.

Setaria verticillata resembles S. adhaerans, but differs in having longer panicles and spikelets, sheath margins that are ciliate distally, and blades that are scabrous, not hairy. Setaria verticillata is a more northern species than S. adhaerans, but their ranges overlap in the Flora region."
