Oplismenus setarius is notable for forming patches of plants with stems and leaves on the ground. The outermost portions of stems rise up and produce several spikelets, each with long awns. Note the transverse ribbing on the leaf surface. Learn more at Vascular Plants of North Carolina.
The "setarius entity" (variously treated at subspecies or species rank) is undoubtedly native in our area, often occurring in undisturbed habitats in natural communities entirely devoid of alien species (though it can also act somewhat aggressively in disturbed sites), per Weakley's Flora (2023).
