DistributionThe BONAP map shows it in 30 counties scattered from the Coastal Plain to the Mountains. Curiously, SERNEC has just one specimen, from Wake County (no date). For the time being, the website editors choose not to map the BONAP counties, as being uncorroborated.

Native of South America; in N.A. recorded only from NC, SC, KY, IL, MO.
AbundanceUnknown; all reported populations have apparently been eradicated. On the federal list of noxious weeds.
HabitatFields and other disturbed areas.
PhenologyFlowering and fruiting June-July.
IdentificationSerrated Tussock is a rather small tussock-former, its leaves only 8-18 inches long. Leaf blades are convolute (rounded in cross-section), stiff, and scabrous. Flowering stems are less than 2 feet tall, the inflorescence occupying much of it, open and sparsely branched. Each spikelet has a single floret with a very long awn.
