Imperata cylindrica (L.)P.Beauv.
COGONGRASS
**
Imperata cylindrica was cultivated in Florida in 1937, and was naturalized by the 1950s in Hernando and Walton counties. Analyses by Burrell et al. (2015) suggest that one clonal lineage (CL2, possibly from the Philippines) is predominant in Florida, with another (CL1, possibly from southern Japan) present in the panhandle.
