General Comments:There is potential name confusion with this species since it was formerly considered to be a subspecies of O. hirtellus (Oplismenus hirtellus subsp. setarius) The Florida Plant Atlas indicates that Oplismenus setarius is common in Florida. O. hirtellus (not the subspecies) has been documented from only one Florida county, and it is a non-native.
