Interpretive Summary: Oklahoma sedge (Carex oklahomensis) is native to Arkansas, Kansas, Missouri, Oklahoma, and Texas. This sedge was discovered new from several states within the past two decades. Oklahoma sedge is reported new for Alabama, Georgia, and Louisiana and new for 3 counties in Mississippi. It is being spread in contaminated hay and seeds of acceptable grasses used for erosion control at construction sites. Currently, this weed is restricted to sites of introduction.
